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 I0 in the light amount distribution thereof on the imaging surface so as to satisfy following condition: 1.2 x P1/2 </= I0 </= 2.5 x P1/2, in which P1/2 is a half decay exposure light amount for decaying the potential of the imaging surface from an initial potential value before the exposure to the half of the initial potential value. <IMAGE>
