20100215395 | REMOVABLE MEMBER-HOLDING DEVICE AND IMAGE FORMING APPARATUS - A removable member-holding device is provided and includes: a pull-out member being movably between an accommodating position and a pull-out position; a holding member supported on the pull-out member and having a holding member body, the holding member being extended in a moving direction of the pull-out member and holding a removable member which is removed from the image forming apparatus body, the holding member being movable between an insertion enabling position and a removing position; and a pull-out regulating member provided on a downstream end of the holding member in the pull-out direction and regulating a movement of the removable member to a downstream side in the pull-out direction. | 08-26-2010 |
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 |
20110064474 | DEVELOPER DELIVERING DEVICE AND IMAGE FORMING APPARATUS - A powder transporting device includes a transporting path that has first and second transporting path transporting paths, a connecting member that is disposed in a connecting portion of the first transporting path and the second transporting path, a sealing member that seals a connection transporting path and the connecting member; an opening that is disposed on an end side of the connection transporting path of the connecting member; a rotation gate member that moves between a rotation blocking position and a rotation opening position; and an outer gate member moves between an outer opening position and an outer blocking position. | 03-17-2011 |
20130195501 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS USING THE SAME - A developing device includes : a first developing body that develops a developing agent image on a development surface using a developing agent; a second developing body that develops a developing agent image on the development surface using the developing agent; and a sealing member that is disposed between a region where a first delivery pole and a second delivery pole are opposed to each other and the development surface, and adjacently to the first developing body and the second developing body at distances so small that developing agents formed as magnetic brushes on a first conveyance pole and a second conveyance pole respectively can touch the sealing member to secure sealing to prevent the developing agent from leaking to the outside of a device body. | 08-01-2013 |
20130195512 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS - A developing device includes a container; a cylindrical first developer-transporting member rotatably supported by the container and whose rotation axis is substantially parallel with a rotation axis of a subjected-to-development member; a first magnet disposed inside the first developer-transporting member and secured to the container; a swinging member supported so as to be capable of swinging relative to the container around the rotation axis of the first developer-transporting member; a cylindrical second developer-transporting member at least one end portion of which is rotatably supported by the swinging member, the second developer-transporting member being adjacent to the first developer-transporting member and rotating in the circumferential direction to transport the developer to the subjected-to-development member; and a second magnet disposed inside the second developer-transporting member and secured to the swinging member. | 08-01-2013 |
20130195514 | IMAGE FORMING APPARATUS - An image forming apparatus includes a housing, a latent image carrier, and a developing device. The developing device includes a container, a supporter, first and second developer-transporting members, first and second magnets, a pair of first urging members, and a pair of second urging members. The pair of first urging members presses the container toward the latent image carrier while being interposed between the supporter and the container. The first urging members serve as two vertexes of a first triangle surrounding the center of gravity of part of the developing device excluding the supporter. The pair of second urging members presses the container toward the latent image carrier while being interposed between the supporter and the container. The second urging members serve as two vertexes of a second triangle surrounding the center of gravity of part of the developing device excluding the supporter. | 08-01-2013 |
20130315635 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS - A developing device includes a first developing roller, a second developing roller, a layer regulation member, a pair of division magnetic poles that divide a developer which is held by the second developing roller after passing through the layer regulation member and transfer the developer to the first developing roller, and a transfer amount regulation member that has a plate shape, is provided in a developer transfer path formed by the pair of division magnetic poles between the first developing roller and the second developing roller so as to extend in an axial direction of the first and second developing rollers, and is provided with a slit which regulates the amount of developer passing therethrough. | 11-28-2013 |
