Abstract
A process cartridge and an image forming apparatus in which a charging roller is separated from a photosensitive drum by a predetermined distance and in which the separation between the charging roller and the photosensitive drum is released at the time of use without involving an increase in the burden on the user and erroneous releasing of the separation by user is prevented prior to use. The process cartridge, which is detachably mountable to the apparatus main body having an acting portion, includes a process cartridge frame, a locking portion locked with the frame to separate the charging roller from the photosensitive drum, a separation holding member having an acted portion which penetrates the frame and on which the acting portion can act, and a protruding portion provided on the frame and protruding beyond the acted portion at the position where the separation holding member is locked with the frame.
