ABSTRACT:
A bet unit provides an intermediate transfer belt where primary transfer is performed at a part stretching between a drive roller and a tension roller, and a cleaner roller separated from and brought into contact with a part of the intermediate transfer belt stretching between an opposed roller and the drive roller in the downstream side of the opposed roller. The belt unit is detachably attachable to the body with the opposed roller on the operator's side. The tangential line of the opposed roller is substantially vertical at a secondary transfer position. The cleaner roller is disposed in a range enclosed by the intermediate transfer belt, the tangential line of the drive roller parallel to the common tangential line of the peripheries of the tension roller and the opposed roller, and the vertical tangential line of the secondary transfer side of the opposed roller.
