| 20090010679 | Image forming apparatus and toner cartridge - A toner cartridge is detachably attached to an image forming apparatus and supplies toner to the image forming apparatus. The locking mechanism is positioned either at a locking position or at a non-locking position. Shortly after the toner cartridge has been attached to the image forming apparatus, the locking mechanism is at a non-locking position. When a user operates a driving member of the toner cartridge after the toner cartridge has been attached to the image forming apparatus, the operating lever engages the locking mechanism to cause the locking mechanism to move to a locking position. When the locking mechanism is at the locking position, the locking mechanism limits the driving member to move relative to the engagement portion, so that the toner cartridge is not allowed to be detached from the image forming apparatus. | 01-08-2009 |
| 20090052935 | CHARGING APPARATUS, IMAGE FORMING UNIT THAT EMPLOYS THE CHARGING APPARATUS, AND IMAGE FORMING APPARATUS THAT EMPLOYS THE IMAGE FORMING UNIT - A charging apparatus includes a charging roller and a cleaning member. The charging roller charges a surface of an image bearing body. The cleaning member extends in a longitudinal direction parallel to the charging roller and that cleans the charging roller. The charging apparatus includes a bearing and a supporting member. The bearing supports a shaft of the charging roller. The cleaning member is mounted to the supporting member the cleaning member is held between the supporting member and the charging roller. The supporting member includes a surface to which the cleaning member is mounted, the surface being a curved surface configured to a circumferential surface of the charging roller. The supporting member includes a surface to which the cleaning member is mounted, the surface including a flat portion extending upstream with respect to rotation of the charging roller and a curved portion extending downstream. | 02-26-2009 |
| 20090263165 | DEVELOPER CARTRIDGE, IMAGE FORMING UNIT AND IMAGE FORMING APPARATUS - A developer cartridge includes an outer barrel member, an inner barrel member rotatably provided with respect to the outer barrel member, and a regulating member rotatably provided with respect to the inner barrel member. The regulating member includes a first engaging portion and a second engaging portion. The inner barrel member includes a first to-be-engaged portion that engages the first engaging portion and an operating member. The outer barrel member includes a second to-be-engaged portion that engages the second engaging portion. When the first engaging portion and the first to-be-engaged portion engage each other and engagement between the second engaging portion and the second to-be-engaged portion is released, the inner barrel member is rotatable together with the regulating member with respect to the outer barrel member. When engagement between the first engaging portion and the first to-be-engaged portion is released and engagement between the second engaging portion and the second to-be-engaged portion released, the regulating member is rotatable with respect to the inner barrel member. | 10-22-2009 |

| 20110103846 | Developer storage container, developing device and image forming apparatus - A developer storage container includes a developer storage portion that stores a developer and has an opening for supplying the developer. An agitating-and-supplying member is rotatably provided in the developer storage portion. The agitating-and-supplying member has a shaft portion and an agitating portion. The agitating portion has a fixed end and a distal end opposite to each other. The fixed end of the agitating portion is fixed to the shaft portion. The agitating portion has an area corresponding to the opening. In the area, a distance between a center axis of the shaft portion and the distal end of the agitating portion is longer than a distance between the center axis of the shaft portion and an outer wall of the developer storage portion. | 05-05-2011 |
