ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND ELECTROPHOTOGRAPHIC DEVICE

摘要

PURPOSE:To provide an electrophotographic photoreceptor whose coupling force to a supporting body is maintained at an enduring time by using an electrophotographic device of a system where a DC and an AC voltages are superimposed and impressed by contact electrostatic charge. CONSTITUTION:As for the electrophotographic photoreceptor 11 used in the electrophotographic device provided with a means which superimposes and impresses a DC and an AC voltages on the photoreceptor 11 by the contact electrostatic charge and having a photoreceptor layer on a cylindrical substrate; the electrophotographic photoreceptor 11 is constituted so that the aperture part thereof is coupled to the supporting member by caulking and the electrophotographic device is provided with the electrophotographic photoreceptor 11. Thus, the electrophotographic photoreceptor 11 whose coupling force to the supporting member is maintained at the enduring time is used in the electrophotographic device of the system where the DC and the AC voltages are superimposed and impressed by the contact electrostatic charge and the electrophotographic device provided with it are realized.
