Abstract
A process cartridge includes a photosensitive drum unit provided with a photosensitive drum that is rotatable about a first rotational axis. The photosensitive drum unit also includes a first positioning portion configured to position the process cartridge to a main assembly in the mounting direction. The photosensitive drum further includes a second positioning portion configured to position the process cartridge to the main assembly so as not to rotate relative to the main assembly. The process cartridge also includes a developing unit including a developing roller rotatable about a second rotational axis, with the developing unit being provided with a storing means having a contact surface. As seen in the direction of the first rotational axis, a first line segment connecting a center of the first positioning portion and a center of the second positioning portion and a first linear line passing through the contact surface and perpendicular to the contact surface intersect with each other at an intersection. The intersection is located at a position closer to the second positioning portion than to the first positioning portion.
