<P>PROBLEM TO BE SOLVED: To provide a process cartridge capable of making smooth the transmission of a driving force from an electrophotographic photoreceptor to a transfer roller on an electrophotographic image forming apparatus main body side. <P>SOLUTION: The process cartridge B, which comprises a main body driving means 31, a transfer roller 4 for transferring a developed image to a recording medium, a transfer roller pulley 60 for driving the transfer roller, and a driving transmission belt 50 which engages the transfer roller pulley to drive the transfer roller, and is detachably loaded in the electrophotographic image forming apparatus main body A forming an image on the recording medium, has the electrophotographic photoreceptor 7, a developing means 22 of developing a latent image formed on the electrophotographic photoreceptor with a developer, a driving reception portion 7a1 which is coupled to the main body driving means to transmit a driving force to the electrophotographic photoreceptor, and a photoreceptor pulley 7b which transmits the driving force that the electrophotographic photoreceptor receives from the driving reception portion to the transfer roller. When the process cartridge is loaded in the apparatus main body, the photoreceptor pulley engages the driving transmission belt to increase the angle of winding between the transfer roller pulley and driving transmission belt. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
