Abstract
An image forming apparatus for forming an image on a recording material. A process cartridge, including a photosensitive drum and a process device actable on the drum, is detachably mountable to a main assembly of the image forming apparatus in a direction of an axis of the drum. The image forming apparatus includes a first positioning portion, provided above the cartridge, for positioning, with respect to a direction crossing with the axis of the drum, the drum at an upstream position with respect to a mounting direction in which the cartridge is mounted to the main assembly of the apparatus, and a second positioning portion, provided above the cartridge at a downstream position with respect to the mounting direction, for positioning the drum with respect to a direction crossing with the axis of the drum. A third positioning portion limits rotation of the cartridge relative to the first positioning portion and the second positioning portion when the main assembly coupling transmits a driving force to the drum coupling and positions the lower portion of the cartridge at an upstream position with respect to the mounting direction.
