ABSTRACT:
An image forming apparatus for forming an image on one or both sides of a recording medium includes a rotatable photoconductive element on which latent images are optically written, a developer which develops the images to produce a primary toner image on the photoconductive element, a belt which faces the photoconductive element, and onto which the toner image is transferred when a paper sheet is not present. A charged roller is close to and above an upper portion of the belt and downstream from the photoconductive element. The charged roller holds the paper on the belt and also transfers toner onto the underside of the paper.
