Cartridge and electrophotographic image forming apparatus

摘要

A cartridge detachably mountable to the main assembly of an electrophotographic image forming apparatus, includes a developing member for developing an electrostatic latent image formed on an electrophotographic photoconductive member; a developer accommodating portion for accommodating a developer to be used by said developing member for developing the electrostatic latent image; a locking portion for engagement with the locking portion of the main assembly of the apparatus to prevent said cartridge from dislodging from the main assembly of the apparatus after mounting of the cartridge; and a releasing portion for disengaging said locking portion of said cartridge from the locking portion of the main assembly of the apparatus when the cartridge is removed from the main assembly of the apparatus.
