Abstract
An image forming apparatus includes: an image forming portion for forming an image; a transferring material conveying belt for conveying a transferring material toward the image forming portion; a driving roller for driving the transferring material conveying belt; a driven roller over which the transferring material conveying belt is looped; and a transferring portion for transferring the image formed by the image forming portion to the transferring material. The transferring material conveying belt is wound and stretched between the driven roller and the driving roller. A rotational axis of the driven roller is different from a rotational axis of the driving roller. Further, a surface of the driven roller includes a layer which has a coefficient of friction lower than a coefficient of friction of a surface of the driving roller.
