Abstract
In order to reduce the cost of a photosensitive member and to prevent the fluctuation in image density and the image smear by highly precise temperature control, the image forming apparatus of the present invention includes: a cylindrical photosensitive member with a conductive substrate having a thickness not smaller than 0.1 mm and smaller than 2.5 mm, and a light-receiving layer having a photoconductive layer on the conductive substrate, the light-receiving layer containing at least amorphous silicon; and a charging device for charging the photosensitive member, wherein the photoconductive layer has a thickness not smaller than 5 .mu.m and smaller than 20 .mu.m, and wherein the charging device is a device for contacting a charging member with the surface of the photosensitive member and applying a voltage to the charging member to charge the photosensitive member.
