ABSTRACT:
An electrophotographic development system preventive of a rolling of paper on a photosensitive drum includes a charging roller for charging the surface of the photosensitive drum with high voltage by a rotation with the photosensitive drum, an exposure unit for producing an electrostatic latent image on the charged part of the photosensitive drum, a developing roller having a thin and uniform toner layer through which the latent image on the photosensitive drum passes to be developed into a visible image, and a transfer roller for transferring the image on a paper, whereby to compulsorily separate the paper rolling up the photosensitive drum.
