An image forming apparatus includes a rotatable belt; an image forming station for forming an image on a belt or on a recording material carried on a belt in a region opposing the belt; a first detector, provided in one of upstream and downstream sides of the region with respect to a rotational direction of the belt, for detecting a position of the belt with respect to a widthwise direction; a second detector, provided in the other of upstream and downstream sides of the region with respect to a rotational direction of the belt, for detecting a moving direction in the region; a steering roller, disposed in the one side with respect to the rotational direction, for correcting a position of the belt with respect to the widthwise direction by inclining; a first controller for controlling an inclination of the steering roller on the basis of an output of the first detector; an adjusting roller, provided in the other of the sides with respect to the rotational direction, for adjusting the moving direction in the region; and a second controller for controlling an operation of the adjusting roller on the basis of an output of the second detector.
