摘要： A process cartridge including a drum cartridge, a developing cartridge, and a waste toner container, is provided. The drum cartridge includes a photosensitive drum including a photosensitive layer and a rotation axis extending in an axial direction, a drum cleaner arranged to contact the photosensitive drum, a cleaner frame configured to accommodate the drum cleaner therein, and a waste toner conveyer tube connected with the cleaner frame. The developing cartridge is movable to be attached to and detached from the drum cartridge and includes a developer roller. The waste toner container is movable to be attached to and detached from the drum cartridge. When the developing cartridge and the waste toner container are attached to the drum cartridge, the waste toner container is connected with the waste toner conveyer tube and is located on an opposite side of the developing cartridge to the photosensitive drum.

摘要： A toner cartridge includes a first casing, a second casing, an auger screw, and a shutter. The first casing has a first internal space. The second casing has: a second internal space smaller than the first internal space; a first opening allowing toner in the second internal space to be discharged; and a second opening allowing air in the second internal space to be sent to an outside. The auger screw is rotatable about a first rotation axis and configured to convey toner in the first internal space to the second internal space. The shutter is rotatable relative to the second casing about a second rotation axis between a first position in which the shutter closes the first opening and a second position in which the shutter opens the first opening. In a state where the shutter is at the second position, the shutter does not close the second opening.

摘要： An image forming apparatus includes a main housing, a drawer, and a cartridge. The drawer is movable between an inside position inside the main housing and an outside position outside the main housing. The cartridge is installable into and removable from the drawer. The cartridge includes a photosensitive drum configured to rotate about a drum axis. The drawer comprises a lock member movable between a lock position in which the drawer is locked to the main housing, and an unlock position in which the drawer is unlocked from the main housing. The cartridge installed in the drawer is rotatable about the drum axis between a first position and a second position. The lock member is positioned in the lock position when the cartridge is positioned in the first position, and positioned in the unlock position when the cartridge is positioned in the second position.
