A developing cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The apparatus includes: a frame; a developing device for developing an electrostatic latent image formed on an electrophotographic photosensitive member; a first projected portion engaging a first positioning portion provided in the main assembly of the apparatus when the cartridge is mounted to the main assembly to position the cartridge; a second projected portion engaging a second positioning portion provided in the main assembly when the cartridge is mounted to the main assembly to regulate rotation of the cartridge about the first positioning portion; and a cartridge guide member contacting a main assembly guide portion to guide the cartridge when the cartridge is mounted to the main assembly. The second projected portion is urged in a direction to contact the second positioning portion when the cartridge is set in the main assembly.
