20080267669 | IMAGE FORMING APPARATUS, REGULATING MEMBER AND CONTAINER - An image forming apparatus includes a container that contains a visualizing agent consumed with an operation of forming a visual image on a recording medium; a holding unit that detachably holds the container; and a regulating unit that is disposed in a packing member for packing the image forming apparatus and engages with a part of the container so as to prevent the container from departing from the holding unit. | 10-30-2008 |
20080279594 | DEVELOPER SUPPLY CONTAINER AND IMAGE FORMING APPARATUS - A developer supply container includes a container body, a developer conveyance member, and a clog prevention member. The container body includes an outlet port and contains and contains developer therein. The developer conveyance member includes a rotational shaft and a conveyance-member body. The conveyance-member body is supported by the rotational shaft and has flexibility. The developer conveyance member is disposed in the container body and conveys the developer to the outlet port for discharge. The clog prevention member is formed in the conveyance-member body in a position corresponding to the outlet port. The clog prevention member goes into the outlet port to protrude to outside of the container body as the rotational shaft rotates. | 11-13-2008 |
20080286012 | DEVELOPER STORAGE CASE AND IMAGE FORMING APPARATUS - A developer storage case includes: a storage case that includes: a developer storage space that stores a developer therein; and a discharge opening that discharges the developer stored in the developer storage space, the storage case defining an opening through which a developer passes into the developer storage space; a delivery member including: a rotation shaft that has one end supported on the storage case; and a main body that is supported on the rotation shaft, and that is disposed in contact with the wall surface of the developer storage space while being flexed, the delivery member delivering the developer stored in the developer storage space to the discharge opening; and an opening closing member that is removably supported on the storage case, and that closes the opening and supporting the other end of the rotation shaft. | 11-20-2008 |
20080286014 | DEVELOPER STORAGE CASE AND IMAGE FORMING APPARATUS - A developer storage case includes: a storage case that includes a discharge opening formed in the horizontal direction side surface thereof, that is formed in a flat shape having a horizontal direction width larger than the vertical direction height thereof, and that stores a developer therein; a delivery member that has a center of rotation disposed shifted to the discharge opening, that is rotatably supported on one end wall of the storage case, and that delivers the developer stored within the storage case; and a drive transmission member that is supported on the end portion of the delivery member, and that drives and rotates the delivery member. | 11-20-2008 |
20100266310 | VISIBLE IMAGE FORMING DEVICE AND IMAGE FORMING APPARATUS - An image forming apparatus includes an image carrier, a developing device, a developer container and a hole connection member. The developing device is provided so as to be movable in a direction in which it comes close to and goes away from the image carrier. And, the developing device develops a latent image formed on the surface of the image carrier into a visible image. The hole connection member is supported so as to be movable relative to an inlet of the developing device in the movable direction of the developing device and connects the inlet and an outlet of the developer container. | 10-21-2010 |
20100316414 | DEVELOPER STORAGE CONTAINER AND IMAGE FORMING APPARATUS - A developer storage container includes a container main body, an outflow port, an open/closed member and a turn stop part. The outflow port from which a developer flows out is formed in the container main body storing the developer. The open/closed member is supported to the container main body and, moves relative to the container main body based on a rotation of the container main body. The open/closed member opens and closes the outflow port. The turn stop part is formed on a wall face of the container main body, and has a circular arc shape being concentric with a rotation direction of the container main body. The turn stop part engages with a convex part which is provided in the attachment section and is formed at a different position in response to the image forming apparatus body. | 12-16-2010 |
20100322666 | DEVELOPER STORING VESSEL AND IMAGE FORMING APPARATUS - A developer storing vessel includes a supplied developer storing portion including: a first supply storing portion which is stored a developer to be supplied to a developer unit; a second supply storing portion which is provided under the first supply storing portion and formed with a horizontal width narrower than that of the first supply storing portion; and a supply outlet from which the developer stored in the second supply storing portion flows out; and a recovered developer storing portion including: a recovery inlet which is disposed above the supply outlet in a direction of gravity, in a position displaced therefrom horizontally and within the horizontal width of the first supply storing portion, and from which recovered developer flows in, and a recovery storing portion which is provided under the recovery inlet and in which the developer flowing from the recovery inlet is stored. | 12-23-2010 |
20110076063 | DEVELOPER STORAGE CASE HAVING A DISCHARGE OPENING OF A FLAT SHAPE - A developer storage case includes: a storage case that includes a discharge opening formed in the horizontal direction side surface thereof, that is formed in a flat shape having a horizontal direction width larger than the vertical direction height thereof, and that stores a developer therein; a delivery member that has a center of rotation disposed shifted to the discharge opening, that is rotatably supported on one end wall of the storage case, and that delivers the developer stored within the storage case; and a drive transmission member that is supported on the end portion of the delivery member, and that drives and rotates the delivery member. | 03-31-2011 |
