Abstract
A tandem electrophotographic image forming apparatus includes plural toner image forming units and a fixing unit. The plural toner image forming units are disposed in a conveyance direction of a printing medium. Each of the toner image forming units includes a photoreceptor on which a toner image is formed and a transfer member to which a transfer voltage is applied to cause the toner image to be transferred from the photoreceptor onto the printing medium. The fixing unit is disposed on a downstream side of the toner image forming units in the conveyance direction of the printing medium and heats and fixes, to the printing medium, the toner images that have been transferred onto the printing medium. The transfer voltages applied to the transfer members are made smaller the closer to the fixing unit.
