ABSTRACT:
A process cartridge includes a photosensitive drum, a photosensitive unit rotatably supporting the drum, and a protecting cover mountable to an electrophotographic image forming apparatus main body, for protecting the drum exposed to the outside of the photosensitive unit. The protecting cover includes a guide for guiding the cartridge to an inside of the main body along a longitudinal direction of the drum, a positioned portion at a leading end of the cover so as to be abutted against a positioning portion of the main body, for positioning the cover in a direction crossing the longitudinal direction, and an engaged portion at the leading end so as to be engaged with an engaging portion of the main body in the inserting direction, for regulating detachment of the protecting cover from the apparatus main body from an upstream side thereof in the insertion direction.
