Abstract

A process cartridge includes a frame body, a substrate having a memory element, and a cartridge electrical contact and a cartridge pushing portion provided on the frame body. An electrophotographic image forming apparatus on which the process cartridge is loaded includes a main body electrical connector and main body electrical contacts. The cartridge pushing portion moves the main body electrical connector so that the process cartridge moves in a direction to be electrically connected with the cartridge electrical contact when the process cartridge is loaded on the electrophotographic image forming apparatus. The cartridge pushing portion operates so as to give a pushing force for pushing the main body electrical contact in a direction to be electrically connected with the cartridge electrical contact. In this way, the main body electrical contact and the cartridge electrical contact can be stably reliably brought into contact.
