Abstract
An image forming apparatus () is equipped with a plurality of photoreceptor drums (A toD), an intermediate transfer belt (), a separating and contacting mechanisms (), a tension roller (), a meandering correction mechanism, and a controller. The separating and contacting mechanism () displaces the intermediate transfer belt (). The meandering correction mechanism increases and decreases a biasing force applied to each of the opposite end portions of the tension roller () according to the amount of movement of the intermediate transfer belt () in the axial direction () of the tension roller (). The controller, during a non-image forming period, at a predetermined timing during rotation of the intermediate transfer belt (), executes a belt displacement process in which the intermediate transfer belt () is displaced from a predetermined reference position and then returned to the reference position.
