PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which makes it possible to obtain stable images free of image defects, such as ghosts, fogging and density unevenness, an electrophotographic device and a process cartridge. SOLUTION: The electrophotographic device which has the photoreceptor, the electrostatic charging means, information writing means, the developing means, the transfer means, developer electrostatic charge quantity control means existing upstream of the electrostatic charging means and electrostatically charging the developer on the photoreceptor surface, and residual developer image uniformizing means existing upstream of the control means and downstream of the transfer means and uniformizing the residual developer image remaining on the photoreceptor surface after the transfer of the developer image and comprises uniformizing the remaining residual developer image after the transfer of the develop or image by the uniformizing means, subjecting the uniformized residual developer to electrostatic charging treatment to a normal polarity by the developer electrostatic charge quantity control means and electrostatically charging the photoreceptor surface and simultaneously regulating the same to the adequate electrostatic charge quantity by the electrostatic charging means and in which the elastic deformation work done We in an indentation test down to a depth of 1 μm in the photoreceptor surface is 35 to 60% of the work done Wt over the entire part of the deformation, the electrophotographic photoreceptor and the process cartridge. |
