A developing device holder, process cartridge, and electrophotographic image forming apparatus

摘要

A developing device holder usable with a process cartridge detachably mountable to a main assembly of an image forming apparatus, the process cartridge including an electrophotographic photosensitive member, developing roller for supplying toner to the electrophotographic photosensitive member to develop a latent image formed thereon and a developing frame for supporting the developing roller, the holder comprises an antenna contact mounting portion for mounting an antenna contact for transmitting an electric signal to a detecting device provided in the main assembly of the electrophotographic image forming apparatus to notify mounting of the process cartridge to the main assembly of the electrophotographic image forming apparatus, wherein the antenna contact mounting portion mounts the antenna contact so as to be exposed from the developing device holder when the developing device holder is mounted to the developing frame; a guiding member for guiding the process cartridge when the process cartridge is mounted to the main assembly of the electrophotographic image forming apparatus, wherein the guiding member is disposed at the same side as a side where the antenna contact is exposed; wherein the developing device holder is mountable to the developing frame of the process cartridge. <IMAGE>
