CARTRIDGE, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

摘要

Provided is a cartridge that can be mounted to and removed from the main body of an electrophotographic image generation device. The cartridge includes: (i) a rotatable development roller for developing a latent image generated on a photosensitive member; (ii) a first driving transfer member for receiving a rotational force generated by the main body of the device; (iii) a second driving transfer member that can be coupled with the first driving transfer member and that can transfer the rotational force received by the first driving transfer member to the development roller; and (iv) a coupling release member that includes a force receiving section that can receive force generated by the main body of the device and an impelling section that can impel at least one of the first driving transfer member and the second driving transfer member with the force received by the force receiving section so as to separate one of the first driving transfer member and the second driving transfer member from the other to release the coupling.
