Abstract
An image forming apparatus includes an image supporting member; a belt; a belt drive unit for rotating the belt; an acceleration and deceleration information storage unit; and a belt speed control unit. The belt speed control unit determines a difference between a first moving amount corresponding to rotations of the image supporting member from a stationary state thereof to a specific speed and a second moving amount corresponding to rotations of the belt from a stationary state thereof to the specific speed. The belt speed control unit controls the belt drive unit, so that a third moving amount corresponding to rotations of the belt from the specific speed to the stationary state thereof becomes larger than a fourth moving amount corresponding to rotations of the image supporting member from the specific speed to the stationary state thereof according to the difference.
