IMAGE FORMING APPARATUS

An image forming apparatus includes a control unit that controls an electric potential difference between a development roller and a supply roller in such a manner that force in a direction from the supply roller toward the development roller acts on toner in a section of an image forming region extending from a leading edge of a first image forming region toward a trailing edge thereof. The control unit controls the electric potential difference in such a manner that force acting on the toner becomes smaller in a section extending from a switching point, which is located at a position obtained by returning from a leading edge of a second image forming region to the first image forming region by a distance equal to or greater than a circumferential length of the development roller, to the trailing edge of the first image forming region.
