Abstract
An image forming apparatus, including a laminate image-bearing member having a dielectric layer or photoconductive layer, superimposed on an electrically conductive substrate, a transfer member for making pressure contact with said image-bearing member, and a cleaning member for cleaning the surface of said image-bearing member through contact therewith, forms an electrostatic latent image on said image-bearing member, develops said latent image into a visible toner image, and transfers said toner image from said image-bearing member to a transfer sheet passing through a contact-pressure nip portion between said image-bearing member and a transfer member by applying a controlled constant-current regulated transfer bias voltage to said transfer member. Where the transfer member is narrower than the dielectric layer, or photoconductive layer, of the image-bearing member and the width of the cleaning member so as to be arranged within said widths, a controller changes the transfer current of constant-current regulated transfer bias in accordance with the thickness of the dielectric layer or photoconductive layer of the image-bearing member.
