置。[Claims for Utility Model Registration] A photoreceptor drum that forms an electrostatic latent image, a charging device that uniformly charges the surface of this photoreceptor drum, and a surface potential of the photoreceptor drum that is charged by this charging device. In an image forming apparatus having a surface potential sensor for measuring the surface potential sensor, a shield plate is formed by the shield plate and the surface potential sensor to prevent the dispersion of corona ion wind generated on the surface of the photoreceptor drum. The coating surface is formed in a rectangular shape over the entire length of the photoconductor drum in the longitudinal direction, and the distance between the coating surface and the surface of the photoconductor drum is arranged to be constant over the entire area of the coating surface. image forming apparatus.
