A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the main assembly including a main assembly electrical contact, a first projection, a second projection, a force application member, a first main assembly positioning portion, a second main assembly positioning portion and a movable supporting member supporting the main assembly electrical contact, the first projection and the second projection, said process cartridge comprising:
- a first frame;
- a second frame rotatably connected with said first frame;
- an electrophotographic photosensitive drum provided in said first frame;
- a first portion to be positioned, being positioned to the first main assembly positioning portion when said process cartridge is set in the main assembly of the apparatus, said first portion to be positioned projecting outwardly from said first frame substantially coaxially with an axis of said electrophotographic photosensitive drum at one end of said first frame with respect to the direction of the axis of said electrophotographic photosensitive drum;
- a second portion to be positioned, being positioned to the second main assembly positioning portion when said process cartridge is set in the main assembly of the apparatus, said second portion to be positioned projecting outwardly from said first frame substantially coaxially with the axis of said electrophotographic photosensitive drum at the other end of said first frame with respect to the direction of the axis of said electrophotographic photosensitive drum;
- a developing roller, contactable to said electrophotographic photosensitive drum provided in said second frame, and configured and positioned to develop an electrostatic latent image formed on said electrophotographic photosensitive drum;
- an elastic member that applies an elastic force to said first frame and said second frame to contact said electrophotographic photosensitive drum and said developing roller to each other;
- a force receiving portion, provided in said second frame, and configured and positioned to receive a force from the force application member to space said electrophotographic photosensitive drum and said developing roller from each other;
- a first regulating portion configured and positioned to engage with the main assembly to regulate the rotation of said first frame about said first portion to be positioned and said second portion to be positioned when said force receiving portion receives the force from the force application member, said first regulating portion being provided in said first frame at one end thereof with respect to the axial direction thereof;
- a second regulating portion provided on said first frame at the other end thereof with respect to the axial direction and configured and positioned to engage with the main assembly with a larger gap than said first regulating portion to regulate the rotation of said first frame about said first portion to be positioned and said second portion to be positioned when said force receiving portion receives the force from the force application member;
- a memory element configured to store information relating to said process cartridge, said memory element being provided at a leading end of said first frame with respect to a mounting direction in which said process cartridge is mounted to the main assembly of the apparatus and being provided at the other end of said first frame with respect to the axial direction;
- a cartridge electrical contact provided at said one end of said first frame at the leading end thereof and configured and positioned to make an electrical connection with the main assembly electrical contact when said process cartridge is set in the main assembly of the apparatus, said cartridge electrical contact being effective to transmit information from said memory element to the main assembly of the apparatus when said cartridge electrical contact is electrically connected with the main assembly electrical contact;
- a first recess provided in said first frame at said one end of said first frame and configured and positioned to position said cartridge electrical contact relative to the main assembly electrical contact when said process cartridge is being mounted to the main assembly of the apparatus, said first recess being engageable with the first projection when said process cartridge is being mounted to the main assembly of the apparatus;
- and
- a second recess provided in said first frame at said one end of said first frame and configured and positioned to position said cartridge electrical contact relative to the main assembly electrical contact when said process cartridge is being mounted to the main assembly of the apparatus, said second recess being engageable with the second projection when said process cartridge is being mounted to the main assembly of the apparatus, said second recess being disposed at a position across said cartridge electrical contact from said first recess,
- wherein when said process cartridge is set in the main assembly of the apparatus, said cartridge electrical contact moves integrally with the main assembly electrical contact by said first recess engaging with the first projection and said second recess engaging with the second projection, upon said first frame rotating about said first portion to be positioned and said second portion to be positioned by said force receiving portion receiving the force from the force application member.
