Abstract
An image forming apparatus includes a stretch roller and a steering roller rotatably supporting an intermediate transfer belt and a control portion executing a meandering control operation of controlling a widthwise position of the intermediate transfer belt by operating a tilting portion tilting the steering roller. The control portion tilts the steering roller to a reference position when transfer biases are applied to first and second transfer members in forming an image to perform the meandering control operation from the reference position. The control portion is also configured to be able to update the reference position stored in a storage portion based on an inclined position of the steering roller during the meandering control operation in the state in which the transfer members are applied.
