20100215407 | REMOVABLE MEMBER-HOLDING DEVICE AND IMAGE FORMING APPARATUS - A removable member-holding device is provided and includes: a pull-out member that is supported so as to be movable between an accommodation position and a pull-out position; a rotatable holder that is supported by the pull-out member so as to be rotatable around a rotation shaft and supported so as to be movable integrally with the pull-out member, and that holds a removable member which is attached to and detached from the image forming apparatus main body, the rotatable holder being movable between an insertion possible position where the pull-out member is movable from the pull-out position toward the accommodation position and an inclined position where the rotatable holder rotates downward in a direction of a gravity around the rotation shaft and is inclined with respect to the insertion possible position; and a regulating member that is disposed at the rotation shaft of the rotatable holder to lessen a movement speed of the rotatable holder when rotationally moving to the inclined position. | 08-26-2010 |
20100221045 | IMAGE FORMING APPARATUS - An image forming apparatus includes: an image forming apparatus body that includes a container attaching portion to which a developer container is removably attached; a container put-on member on which the developer container is put; and a support member to which the container put-on member is attached, the support member supporting the container put-on member to perform a movement between a first position in which the container put-on member is at the container attaching portion and a second position in which the container put-on member is pulled out from the container attaching portion, wherein at the second position, at least a part of the container put-on member is displaced downward through a rotating shaft provided on the support member to a lower position than a height of the container put-on member at the second position in the direction of gravity. | 09-02-2010 |
20110076061 | POWDER STORAGE CONTAINER AND IMAGE FORMING APPARATUS USING THE SAME - A powder storage container includes a container body, an opening formed in a portion of the container body, an opening-and-closing cover, a cover holding frame, a protrusion portion provided in the opening-and-closing cover, a blocking portion provided in the cover holding frame, a position regulating protrusion protruding from the cover holding frame, and a disengagement suppressing protrusion provided in the opening-and-closing cover. When the opening-and-closing cover takes such an attitude that the opening-and-closing cover is swingably supported by a contact portion, serving as a fulcrum, between the disengagement suppressing protrusion and the cover holding frame and is arranged along the opening-and-closing operation direction, a distal end position of the protrusion portion is located in a position where the distal end position can be released from the blocking portion. | 03-31-2011 |
20120125944 | POWDER CONTAINER, POWDER PROCESSING APPARATUS USING THE SAME, AND POWDER CONTAINER CONTROLLING METHOD - A powder container includes a container body having an opening corresponding to a powder opening of a container receiver; an open/close lid that closes the opening; a first restricting portion inclined to face a contact surface, which is located upstream of the powder opening and inclined with respect to an open/close operation direction of the open/close lid, when the container body is attached to the container receiver, the first restricting portion contacting the contact surface to restrict a position of the open/close lid in the open/close operation direction; and a second restricting portion restricting a posture of the open/close lid with respect to the container receiver in a direction in which the first restricting portion is tilted down toward the contact surface, when the container body is attached to or detached from the container receiver and a press member restricts movement of the open/close lid. | 05-24-2012 |
20120132559 | POWDER CONTAINER, POWDER PROCESSING APPARATUS USING THE SAME, AND POWDER CONTAINER CONTROLLING METHOD - A powder container includes an open/close lid that closes an opening partly formed in a container body corresponding to a powder opening of a container receiver; a first restricting portion that, upon attachment of the container body to the container receiver, contacts a contact surface formed upstream of the powder opening to restrict a position of the lid in an open/close operation direction thereof; a flexible sealing member that protrudes from an opening-side edge of an open position, and closes an opening-side portion of a gap between the contact surface and the first restricting portion; and a second restricting portion that, upon detachment of the container body, when a press member restricts movement of the lid, restricts a posture of the sealing member so as to be pressed against an edge portion of the powder opening at a position where the first restricting portion contacts the contact surface. | 05-31-2012 |
20120222776 | POWDER CONTAINER AND POWDER PROCESSING APPARATUS - A powder container includes a container body that can be attached to and detached from a powder processing apparatus and that includes an outer wall having an opening; a lid that covers the opening and that is held by a lid holder such that the opening is not covered by the lid when the container body is attached to the powder processing apparatus; a retaining frame that projects from the periphery of the opening and retains the lid in a movable manner; and a suppressing body that projects from the lid by an amount set such that the suppressing body does not come into contact with the outer wall when the lid is moved and such that, if the lid is inclined while being held, the suppressing body comes into contact with the outer wall to suppress the inclination of the lid before the lid is released. | 09-06-2012 |
20130108327 | IMAGE FORMING APPARATUS AND TONER SUPPLY DEVICE | 05-02-2013 |
20130195484 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image carrier that carries an electrostatic latent image; a developer supplying unit that supplies developer by being driven at a predetermined speed; a developing unit that develops the electrostatic latent image, while a transporting member transports the developer, a transport speed of the transporting member being switched to a plurality of speeds; a determining unit that determines whether or not an operation where a supply capacity of the developer supplying unit is greater than a transport capacity of the developing unit exceeds a predetermined threshold value and is continued; and a controller that performs control so that, when the determining unit determines that the operation exceeds the predetermined threshold value and is continued, an operation that was being executed immediately prior to the determination is stopped to forcefully drive the transporting member of the developing unit for a predetermined driving time. | 08-01-2013 |
20150016848 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS - A developing device includes a developer carrier that has a cylindrical shape and that rotates while carrying developer to supply the developer to an image carrier on which an electrostatic latent image is formed, a container that contains the developer carrier, and a discharge-path forming member that is provided along an outer peripheral surface of the developer carrier, that covers a top portion of a path along which the outer peripheral surface moves, the top portion being located at an uppermost position of the path, and that forms a discharge path, through which air is discharged from inside of the container to outside of the container, between the discharge-path forming member and an inner wall surface of the container, the discharge path having an outlet located closer to the developer carrier than the top portion. | 01-15-2015 |
