Abstract
A process cartridge attachable/detachable to/from an apparatus main body of an electrophotographic image forming apparatus is configured such that the photosensitive unit and the development unit are coupled with each other at both ends in a direction parallel to a rotational center axis line of the photosensitive drum. Guide units are provided at one end of the photosensitive unit and at one end of the development unit, which are separated from each other when an external force does not work on the process cartridge. When the process cartridge is subjected to an impact in a direction in which the development roller approaches the photosensitive drum, the guide units are brought into contact with each other while the development unit rotates relative to the link member, and guide the development unit in a direction in which the development roller separates from the photosensitive drum.
