Abstract
A transverse-type image forming apparatus in which a toner image carried on an endless toner image carrying belt is transferred to a printing paper by a transfer facing roller provided inside the toner image carrying belt and caused to move along the printing paper. A transfer bias voltage is applied to a transfer plate, on which the printing paper is set, during the backward movement of, or during both the forward and backward movements of, the transfer facing roller, so as to cause the toner image to be electrostatically attracted to the printing paper. The uneven transfer of the toner image is reduced.
