Abstract

PURPOSE: To make the amount of an electric charge constant at all times despite the occurrence of contamination of wire as well as change of characteristic of photoreceptor, and prevent the deterioration of typing quality by measuring the surface potential of the photoreceptor after having charged, and controlling the voltage of an electric power used for charging with the surface potential.
