ABSTRACT:
A process cartridge is configured to be mounted in an apparatus main body along a predetermined mounting direction. The process cartridge includes: a photosensitive drum; a drum drive input member into which a driving force for rotating the photosensitive drum is inputted; and a frame which holds the photosensitive drum and the drum drive input member; the frame including: a substantially cylindrical first protecting member which is formed on the frame. The first protecting member is configured to accommodate the drum drive input member, and project in a rotational axis direction of the photosensitive drum, wherein a projecting amount of a portion of the first protecting member which lies at a downstream side in the mounting direction is smaller than a projecting amount of a portion of the first protecting member which lies at an upstream side in the mounting direction.
