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 |

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 |
20120328336 | ROTATION TRANSMISSION UNIT, REPLACEMENT UNIT, DEVELOPER CONTAINER AND IMAGE FORMING APPARATUS - A rotation transmission unit includes a driving unit that provides a rotational power; a rotation transmission member that is rotated due to reception of the rotational power transmitted from the driving unit; a rotation member that is rotated due to reception of a rotation of the rotation transmission member; a locking groove that is formed at one of the rotation transmission member and the rotation member; and a locking member that is arranged at the other of the rotation transmission member and the rotation member. Wherein, a surface of the locking member on the locking groove side is plane. | 12-27-2012 |
20130259495 | DEVELOPER STORAGE BODY, DEVELOPER COLLECTING APPARATUS AND IMAGE FORMING APPARATUS - A developer storage body includes a developer storage portion configured to store a developer. The developer storage portion has a first end portion and a second end portion opposite to each other. A developer ejecting portion is provided in the developer storage portion is located closer to the first end portion than to the second end portion. The developer ejecting portion is configured to eject the developer into the developer storage portion. The developer storage body further includes a developer pushing portion configured to push the developer ejected into the developer storage portion from the developer ejecting portion toward the second end portion. A developer detecting portion is provided in the developer storage portion and is located closer to the second end portion than to the first end portion. | 10-03-2013 |
