ABSTRACT:
An image forming apparatus includes an image carrier, a charging unit configured to charge the image carrier, an exposing unit configured to form an electrostatic latent image on the charged image carrier, a developing unit configured to develop the electrostatic latent image formed on the image carrier with a development material for forming a development image, an intermediate transfer member that includes a multilayer structure having a conductive layer;a transfer unit configured to transfer the development image on the intermediate transfer member, and a control unit that controls a transfer potential and a charging potential so that a potential difference between the transfer potential and a non-image portion potential on the image carrier in a transfer position falls within a predetermined range.
