PROJECT CARTRIDGE, TECHNOLOGICAL CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE

摘要

1. A removable process cartridge (7) installed in a main unit (100A) of an electrophotographic image forming apparatus including a drum connecting member (66), a developing connecting member (53) and an abutment element (85), said process cartridge comprises: (i) a photosensitive drum (1); (ii) a connecting part (1c) of a drum provided adjacent to one axial end of said photosensitive drum, configured and positioned to engage a connecting element of the drum for perceiving the driving force for rotation of said photosensitive drum; (iii) a developing roller (25) configured and positioned for: (a) developing a latent electrostatic image formed on said photosensitive drum, and (b) rotating around its axis ( 25k); (iv) a developing connection part (48) provided adjacent to one axial end of said developing roller, wherein said developing connection part includes: (iv-i) engaged part (48c) configured and positioned to: (a) engage with the drum coupling to receive a driving force to rotate said developing roller and (b) move in a direction transverse to the axis of said developing roller with respect to said developing roller; (v) compressing portion (54) configured and positioned to clamp said engaging portion in a direction transverse to the axis of said developing roller to engage said engaging portion with developing
