ABSTRACT:
An image forming apparatus comprising an image holding member that is rotationally driven, the image holding member comprising, on a substrate, a subbing layer and a photosensitive layer, a volume resistance value of the subbing layer decreasing in a rotation axis direction of the image holding member, from one end portion of a light source side of the image holding member towards another end portion of the image holding member, a charging unit, a latent image formation unit, a developing unit, a transfer unit, and a charge removal unit comprising a light source that, after transfer of the toner image, irradiates the surface of the image holding member from one side thereof, in a rotation axis direction of the image holding member, with charge removing light, to remove the charge from the surface of the image holding member.
