Developing device, process cartridge and electrophotographic image forming apparatus

摘要

A process cartridge datably mountable to a main assembly of an electrophotographic image forming apparatus featuring a connector portion for transmitting a result of detection by a detecting member to a main assembly of the apparatus by electrical connection to the main assembly of the apparatus. A photosensitive member driving force receiving portion, a developing member driving force receiving portion, a developing bias contact and the connector portion are disposed at a leading end of the process cartridge when the process cartridge is mounted to the main assembly of the apparatus. The connector portion and the developing bias contact are disposed with the developing member driving force receiving portion therebetween. The process cartridge is mounted to the main assembly of the apparatus along a longitudinal direction of the developing member.
