发明名称 SUPPORTING MECHANISM FOR ROTARY BODY, PROCESS CARTRIDGE AND ELECROPHOTOGRAPHIC IMAGE FORMING DEVICE
摘要 PROBLEM TO BE SOLVED: To make a shaft member being force-fitted in a frame body possible to be easily withdrawn, and to make a photoreceptor so as to be easily load/unloaded, by providing an opening on an end part of a shaft material in the shaft direction and a notch to the force-fitting part of the frame body in which the shaft member is force-fitted. SOLUTION: The photoreceptor drum 8 is supported in freely rotationally corresponding to the frame bodys 13, by fixing while force-fitting shaft members 19 and 119 in the respective fit-opening 20b of force-fitting parts 20 severally provided in the frame body 13 of a process cartridge, and severally putting the shaft member in the respective opening 16c of flanges 16a and 16c on either end of the photoreceptor drum 8. In the meantime, two notches 120a are formed on either symmetrical section on the outside end part of the force-fitting part 20 on the non-driven side, and another notch 20a is disposed on the outside end part of the force-fitting part 20 of the driven side. Then, at the time of replacing, the photoreceptor drum 8 can be withdrawn from the force-fitted part 20, by making a tool such as radio cutting pliers introduced into the notch 20a on the driven side, and clamping a peripheral part of the shaft member 19 and the opening 19a disposed in the shaft direction on the end part of the shaft member 19, and while clamping the periphery of the shaft member 119 through the notches 120a as for the non-driven side.
