Abstract
A process cartridge for an image forming apparatus includes a drum unit supporting a photosensitive drum; a developing roller; a driving roller for driving the roller; a drive receiving portion; a developing unit supporting the developing roller and the driving roller; and a connecting portion connecting the drum unit and the developing unit, the connecting portion being disposed below the driving roller. The developing unit is movable relative to the drum unit by rotating about the connecting portion between a contacting position in which the drum and the developing roller contact each other and a spacing position in which the drum and the developing roller are spaced from each other. A direction of the receiving portion is opposite to that of the developing roller, and is the same as the developing unit rotation from the spacing position toward the contacting position.
