Process cartridge and image forming apparatus

An electrophotographic image forming apparatus, for forming an image on a recording material, to which a process cartridge is detachably mountable, said apparatus comprising:

• (i) a main assembly positioning portion provided in a main assembly of said apparatus;
• (ii) an urging member;
• (iii) mounting means for detachably mounting the process cartridge, said process cartridge including an electrophotographic photosensitive drum, process means actable on the electrophotographic photosensitive drum, a cartridge positioning portion configured and positioned to engage said main assembly positioning portion to position the process cartridge with respect to a direction crossing the direction of the axis of the electrophotographic photosensitive drum, when the process cartridge is mounted to the main assembly of said apparatus in a direction parallel with the axis of the photosensitive drum, and a movable member provided at a downstream portion of the process cartridge with respect to a mounting direction in which the process cartridge is mounted to the main assembly of said apparatus, the movable member being movable between a first position at which the movable member contacts the main assembly of said apparatus in the mounting direction in the process of mounting of the process cartridge to the main assembly of said apparatus, and a second position in which the movable member is contacted by said urging member provided in the main assembly of said apparatus and receives a force in the crossing direction so as to contact the cartridge positioning portion to said main assembly positioning portion to position the process cartridge in the crossing direction, when the process cartridge is mounted to the main assembly of said apparatus;
• and
• (iv) feeding means for feeding the recording material.
