Abstract
The invention provides a method of forming an image on an imaging surface of a photoreceptor having a light decay characteristic so that the potential of the imaging surface is slowly decayed in an initial period of exposure and the potential of the imaging surface is sharply decayed in a middle period of exposure. The imaging surface is charged to an electric potential, exposed with a light beam, wherein the light beam has the maximum light amount I.sub.0 in the light amount distribution thereof on the imaging surface so as to satisfy following condition:
