Abstract
An image forming apparatus has a transfer region located between a first belt and a second belt, which belts are respectively spanned and tensioned around a plurality of rollers. A total length of the first belt is substantially equal to integral multiples of a total length of the second belt. Certain portions of the belts are deformed via plastic deformation caused by contacting the plurality of rollers. The rollers are arranged so that deformed portions of the belts do not overlap each other in the transfer region.
