摘要： PROBLEM TO BE SOLVED: To reliably prevent charging means from separating from a photoreceptor due to a turned cleaning blade, without requiring special configuration or increasing cost, thereby reliably preventing a full-page solid image from being generated due to the separation.SOLUTION: A photoreceptor 2 includes: a photoreceptor tube 2a having an outer peripheral surface in contact with a tip 5b of a cleaning blade 5; and an end member 2b connected to an axial end of the photoreceptor tube 2a with a predetermined connection force, and receiving rotation torque for rotating the photoreceptor tube 2a. A maximum torque to be transmitted from the end member 2b to the photoreceptor tube 2a is limited by limiting the connection force to a predetermined magnitude. When the rotation torque to be generated between the end member 2b and the photoreceptor tube 2a exceeds a predetermined value as a frictional coefficient between the photoreceptor tube 2a and the cleaning blade 5 increases, slip occurs between the end member 2b and the photoreceptor tube 2a.
