Abstract
An image forming apparatus includes an image forming unit, a belt position detection unit to detect a position of a transfer belt in a rotating shaft direction of a driving roller, and a roller driving unit to tilt a steering roller to control the position of the transfer belt in the rotating shaft direction of the driving roller. In addition, a storage unit stores a reference position of the steering roller and a reference position of the transfer belt, and a control unit controls a formation position of the latent image, in a rotation axis direction of each photosensitive member, formed on each of a plurality of photosensitive members by the image forming unit based on a position of the transfer belt, in the rotating shaft direction of the driving roller, with respect to a detected reference position of the transfer belt and a tilt amount of the steering roller controlled by the roller driving unit with respect to the reference position of the steering roller.
