Abstract: A cartridge including a photosensitive drum, a cleaning unit that supports the photosensitive drum, a process member that acts on the photosensitive drum, the cartridge being detachable from a main body of the image forming apparatus in a rotational axial direction of the photosensitive drum. The cartridge further including a first position determination position determining a downstream position with respect to the main body in a mounting direction of the photosensitive drum, and a second position determination portion that determines an upstream position with respect to the main body in the mounting direction. Furthermore, in a cross section orthogonal to the mounting direction, a distance from an axis of rotation of the photosensitive drum to the second position determination portion in a predetermined direction is larger than a distance from the axis of rotation to the first position determination portion in the predetermined direction.

Abstract: A process cartridge comprises a photosensitive drum and a developing roller. A coupling member is provided adjacent to one axial end of the developing roller. The coupling member includes a driven portion, and an intermediary portion configured and positioned to engage with the driven portion. The intermediary portion is also configured to be movable relative to the driven portion in a direction crossing the axis of the developing roller while maintaining engagement with the driven portion. The coupling member further includes a driving portion configured and positioned to receive a driving force for rotating the developing roller. The driving portion is also configured to engage with the intermediary portion, and to be movable relative to the intermediary portion in a direction crossing the axis of the developing roller while maintaining engagement with the intermediary portion.
