Cartridge and electrophotographic image forming apparatus

An electrophotographic image forming apparatus for forming an image on a recording material, the apparatus comprising:

• i) a main assembly including a photosensitive member on which a latent image is capable of being formed, and the main assembly including a main assembly driving shaft;
• and
• ii) a cartridge mountable, along a predetermined mounting path, to the main assembly, the cartridge being movable in the main assembly between a developing position at a terminal end of the mounting path and a spaced position moved from the developing position in a direction different from a direction of the mounting path, the cartridge including:
• ii-i) a developer carrying member capable of developing the latent image while being in contact with the photosensitive member when the cartridge is in the developing position, and the developer carrying member being capable of being spaced from the photosensitive member when the cartridge is in the spaced position;
• and
• ii-ii) a coupling member capable of inclining relative to a rotational axis of the developer carrying member, the coupling member being capable of taking a reference position in which drive transmission is capable from the main assembly driving shaft to the developer carrying member when the cartridge is in the developing position, an at-dismounting position inclined relative to the rotational axis of the developer carrying member to disengage from the main assembly side driving shaft when the cartridge is dismounted from the main assembly by being moved along the mounting path from the developing position in a direction opposite from a direction the cartridge moves when mounting to the main assembly, and an at-spaced position inclined relative to the rotational axis of the developer carrying member in a direction different from that in the at-dismounting position to disengage from the main assembly side driving shaft when the cartridge is moved from the developing position to the spaced position.
