Abstract
An image forming apparatus sequentially transfers toner images formed on a plurality of photosensitive drums onto an intermediate transfer member or a transfer material to form an image. The image forming apparatus includes an intermediate transfer belt provided with electrical conductivity, and a power supply for applying a voltage to a current supply member contacting the intermediate transfer belt to pass a current from the current supply member to the plurality of photosensitive drums via the intermediate transfer belt, thus generating electric discharge on the upstream side of each of primary transfer sections.
