Abstract
In an electrophotographic image forming apparatus, a potential measurement device for measuring the surface potential of the electrostatic latent image and a reflective density measurement device for measuring the density of a visible image developed from the latent image are made movable, in mutually synchronized manner, along the axial direction of the rotating photosensitive member. In this manner the image forming ability can be measured over the entire surface of the photosensitive member, and the process conditions can be suitably regulated according to the results of measurements.
