Abstract
An image forming apparatus for forming an image on a recording medium includes a belt configured to travel rotationally and looped around at least two rotary support members, a driven rotary member disposed facing at least one of the rotary support members via the belt and configured to rotate with the belt, and a controller. The controller is configured to minimize fluctuation in one of a travel velocity and a travel distance of the belt by controlling the travel of the belt based on one of a rotational angular displacement and a rotational angular velocity of each of the rotary support member and the driven rotary member.
