摘要：
A process cartridge comprises a photosensitive drum, a developing roller, and a coupling member. The coupling member is capable of inclining relative to the photosensitive drum such that the coupling axis inclines relative to the drum axis. A regulating portion surrounds the coupling member so as to confine the range of inclination of the coupling member. The regulating portion is provided with a recess that recesses in a direction away from the drum axis and away from the developing roller. An angle between the coupling axis and the drum axis is larger when at least a part of the coupling member is in the recess than when the coupling member contacts another portion of the regulating portion.
