    摘要: A photosensitive drum is rotatably supported in a main body. A developing cartridge is detachably mountable on the main body in a state where the photosensitive drum is supported in the main body. The developing cartridge includes a developing device and a frame. The developing device includes a developing roller disposed in confrontation with the photosensitive drum to supply developer to the photosensitive drum when the developing cartridge is mounted in the main body, and a developer-accommodating portion configured to accommodate developer. The frame includes a waste-developer-accommodating portion configured to accommodate waste developer and supports the developing device that is movable relative to the frame. The frame is disposed on an opposite side of the developing roller from the photosensitive drum. An urging member is disposed between the frame and the developing device to urge the developing roller toward the photosensitive drum.

    摘要: An image forming apparatus includes: a main body; a photosensitive drum rotatably supported in the main body; a developing unit detachably accommodated in the main body in a direction along an axis of the photosensitive drum in a state where the photosensitive drum is disposed in the main body. The developing unit includes: a developer carrying member configured to carry developer for supplying the developer to the photosensitive drum; a developing frame supporting the developer carrying member; and a supporting assembly configured to support the developing frame such that, in a state where the developing unit is accommodated in the main body, the developing frame is movable between a proximity position where the developer carrying member and the photosensitive drum being positioned adjacent to or in contact with each other and a separation position where the developer carrying member and the photosensitive drum being separated from each other.

    摘要: A sheet feeding apparatus includes a first drive roller and a second drive roller disposed downstream of the first drive roller and configured to rotate at a peripheral speed greater than a peripheral speed of the first drive roller. The first drive roller includes a drive shaft and a roller portion. The roller portion is configured to contact the sheet and is movable relative to the drive shaft in an axial direction and a rotation direction of the drive shaft. One of the drive shaft and the roller portion of the first drive roller includes a protrusion protruding toward the other one of the drive shaft and the roller portion. The other one of the drive shaft and the roller portion of the first drive roller includes a recessed portion. The recessed portion includes a peripheral wall that defines an opening such that the protrusion is positioned in the opening.
