Abstract
Official abstract text for this publication.
A developing cartridge includes an electrophotographic photosensitive member, and a developing roller for contacting the electrophotographic photosensitive member to develop an electrostatic latent image formed on the electrophotographic photosensitive member. The developing cartridge also includes a force receiving portion, projected in an axial direction of the developing roller, for receiving a force for spacing the developing roller and the electrophotographic photosensitive member.
