전자 사진 화상 형성 장치의 회전력 전달부와 결합하는 경사 움직임 가능한 커플링 부재를 채용한 카트리지 구성에 있어서, 그 카트리지가, 전자 사진 화상 형성 장치에 대해 착탈 방향과 현상/이간 방향이 다른 경우, 커플링 부재가 전자 사진 화상 형성 장치의 회전력 전달부와 결합할 수 없다. 그러므로, 현상 카트리지(B1)의 착탈 조작에 연동하여, 커플링 부재(180)에 대해 접촉과 퇴피를 행하는 커플링 레버(55)와, 커플링 레버(55)가 커플링 부재(180)에 가압력을 작용시키는 커플링 스프링(56)을 설치하였다. The present invention relates to a cartridge, mountable to a main assembly of the electrophotographic image forming apparatus including a main assembly driving shaft, comprising: a photosensitive member; a developer carrying member capable of developing a latent image and being movable between a developing position contacting the photosensitive member and a retracted position retracted from the contacting position; and a coupling member capable of inclining relative to a rotational axis of the developer carrying member. The coupling member is capable of taking a reference attitude in which the drive transmission is capable from the main assembly driving shaft to the developer carrying member when the developer carrying member is in the developing position in a state that the cartridge is mounted at a terminal end of a mounting path, an at-mounting attitude inclined relative to the rotational axis of the developer carrying member to engage with the main assembly driving shaft when the cartridge moves along the mounting path, and an at-spaced attitude inclined relative to the rotational axis of the developer carrying member in a direction different from that in the at-mounting attitude to engage with the main assembly side driving shaft when the developer carrying member moves from the retracted position to the developing position in the state that the cartridge is mounted at the end portion of the mounting path.
