Abstract
The present invention relates to an image forming apparatus for a copying machine, a printer, etc., which is provided with an electrifying member disposed opposite to the surface of a photosensitive body and electrifying the surface thereof by applying electric charge thereto. An electrifying member disposed opposite to the surface of a photosensitive body and electrifying the surface thereof by application of electric charge has a curved or flat face along the surface of the photosensitive body and resistance from 10.sup.5 to 10.sup.10 ohms, and at the same time the electrifying member is disposed about 350 .mu.m to about 1000 .mu.m from the surface of the photosensitive body. The electrifying member may be curved to meet the curvature of the surface of the photosensitive body. A conductive portion to apply voltage to the electrifying member may be formed at the side of the electrifying member, which is opposite to the side facing the surface of the photosensitive body. Still furthermore, the electrifying member may be supported by the conductive portion formed at the electrifying member.
