ABSTRACT:
A belt slippage correcting device and method for correcting slippage of a belt which is transported in a predetermined direction. The belt slippage correcting device has a slippage detecting device for detecting slippage of the belt in a direction perpendicular to the belt transporting direction and a moving device for moving the belt in the direction perpendicular to the belt transporting direction and control device for controlling the moving device based on the detected slippage of the belt by the belt slippage detecting device The slippage of the belt is corrected while the moving velocity of the belt in the direction perpendicular to the belt transporting direction is maintained within a predetermined scope of velocity. The device and method may be used in an image forming apparatus, such as an electrophotographic image forming apparatus.
