Abstract

See full text

An image forming apparatus includes a photosensitive drum for bearing a toner image, a rotatable endless belt provided so that its outer surface opposes the drum, and a rigid transfer roller, provided so as to contact an inner surface of the belt, for transferring the toner image from the drum onto the belt or a recording material conveyed by the belt. A coefficient of static friction of a surface of the transfer roller is smaller than that of the inner surface of the belt. In addition, a stretching roller is provided so as to contact the inner peripheral surface of the belt for stretching the belt, with a coefficient of static friction of a surface of the stretching roller being larger than that of the inner peripheral surface of the belt. A cleaning member cleans the surface of the stretching roller.
