ABSTRACT:
Without using corona charge, a predetermined voltage is applied to all of the island-like electrodes provided on a front surface of an electrostatic latent image forming member, which is then exposed by exposing device from a rear surface thereof. Consequently, a contrast potential is generated between the island-like electrodes two-dimensionally arranged, thereby forming an electrostatic latent image. By setting the exposing light-emitting diode array inside the electrostatic latent image forming member, the light irradiating position and the developed position can be made close to each other. Therefore, the latent image can be developed by toner at the maximum contrast potential of the electrostatic latent image on the image forming member. The toner image is then transferred and fixed on an image formation medium.
