An image forming apparatus includes a bias controller that controls a first application unit that applies a bias to a transfer member. The bias controller applies a reverse bias to the transfer member when a first region passes through a nip part. Then, when a second region passes through the nip part, the bias controller applies a fixed first forward bias to the transfer member. When a third region passes through the nip part, in order to implement the control the bias controller applies a variable second forward bias to the transfer member. The first forward bias is set at a predetermined value or above and increases a potential of the transfer member 46 to a level at which a toner image is transferred in the second region when the second region passes through the nip part. |
