In an image forming apparatus comprising an intermediate transfer belt (4) in a form of endless loop stretched over a plurality of stretch roller to move around, a plurality of photo conductors (9) aligned along the intermediate transfer belt, a plurality of primary transfer rollers (6Y) which respectively opposes to the photoconductors and is pressed against the photoconductor with interposition of the intermediate transfer belt to form a nip, and a power source for applying a voltage to the primary transfer rollers, the primary transfer rollers (6Y) being arranged to be shifted with reference to the photoconductors (9) in the moving direction of the intermediate transfer belt (4), a shifted amount (D) of at least one of the primary transfer rollers (6Y) with reference to the photoconductor (9) is different from that of another primary transfer roller with reference to the respective photoconductors.
