An image forming apparatus has: an intermediate transfer member to which a primary transfer voltage having a positive polarity is applied and the toner image is primarily transferred in which a reverse voltage having a negative polarity is applied; a primary transfer device which primarily transfers the toner image by applying the primary transfer voltage; a secondary transfer device which secondarily transfers the toner image by applying a secondary transfer voltage; and a resistance adjusting device which controls at least either the primary transfer device or the secondary transfer device in such a manner that while the intermediate transfer member rotates once, a first correction voltage is applied to the area where the primary transfer voltage has been applied and a second correction voltage higher than the first voltage is applied to the area where the reverse voltage has been applied.
