DRUM UNIT, DRIVE TRANSMISSION UNIT, CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

Abstract: a drum unit for a cartridge includes a photosensitive drum and a flange positioned at an end of the photosensitive drum coaxially with the photosensitive drum to transmit a driving force to the photosensitive drum. a first coupling is supported by the flange such that at least a part of the first coupling is exposed from the flange to receive the driving force, with the first coupling being inclinable relative to the flange. a second coupling operatively connected to the first coupling and the flange to transmit the driving force from the first coupling to the flange.
