Abstract

PURPOSE: To obtain a good image of copy free from the ground stain in the electrophotography by previously measuring the electric potential of an electrostatic latent image formed by the reflecting light by the use of a reference plane, and by setting the maximized amount of exposure or bias voltage of development based on the above.
