摘要： An image forming apparatus includes an image bearing member; a rotatable belt member; a rotatable supporting roller for stretching the belt member; and a steering roller controlled by motors for stretching the belt member and for moving the belt member in a widthwise direction by an inclining operation. A number of sensors detect the position of the belt member in the widthwise direction and produce an output, causing a first controller to change the amount of the inclining operation of the steering roller in order to counter the force moving the belt member in the widthwise direction. The output of the sensors also causes a second controller to change the amount of the inclining operation of the steering roller in short intervals to reduce the rapid positional deviation of the belt member attributable to the inclination of the steering roller.
