摘要： PURPOSE:To obtain copied pictures of high quality for a long period of time by performing the electrostatic charging with the adverse polarity to the electrostatic charging carried out when an electrostatic latent image is formed or the electrostatic charging due to an AC and the uniform irradiation of light and then performing the uniform electrostatic charging and picture exposure for formation of an electrostatic latent image. CONSTITUTION:The electric charge having the adverse polarity as a main corona electrifier 41 is applied to a control corona electrifier 47. A photosensitive body 40 is electrostatically charged with negative polarity by the electrifier 47 after the development, copying and cleaning processes, and the negative cgarge is applied to the surface of an overcoat layer of the body 40. Thus the positive electric charge is induced to a conductive substrate. Then the body 40 is irradiated evenly by a light eraser 48, and positive and negative charge carriers are generated inside a photoconductive layer at an area near the interface of the overcoat layer. The positive carriers neutralize the negative carriers stored on the interface; while the negative carriers are guided by the positive charge of the substrate and get away toward the substrate. As a result, the charge carriers on the interface are erased for each copy.
