Abstract
An image forming apparatus includes: a rotating belt which rotates around a roller; a drive section which rotates the belt; a detection section which detects a position of the belt in a width direction; a moving section which moves the belt in the width direction; a control section which corrects a deviation of the belt by controlling the moving section. The control section conducts a preparatory operation in which the control section changes an amount of control to be given to the moving section under the condition where the belt is rotated to obtain a correction data showing a relation between the amount of control and a change of a position of the belt in the width direction detected by the detection section, stores the correction data in a memory section, and then corrects the deviation based on the correction data stored in the memory section.
