摘要

The present invention provides a process cartridge detachably mountable to a main body of an electrophotographic image forming apparatus, comprising a first frame for supporting an electrophotographic photosensitive drum and a developer bearing member for developing a latent image formed on the electrophotographic photosensitive drum with a developer, and a second frame having a developer containing portion containing the developer for developing the latent image formed on the electrophotographic photosensitive drum and detachably mountable to the first frame. A mounting and dismounting direction of the second frame with respect to the first frame is transverse to an axial direction of the electrophotographic photosensitive drum.
