Abstract

A fixing device including a fixing belt, a drive roller and a press roller. The drive roller is configured to drive the fixing belt, and press roller is arranged so as to face the drive roller across the fixing belt, and exert pressure toward the fixing belt. The drive roller and the press roller are able to rotate so that the peripheral velocity of the drive roller is greater than the peripheral velocity of the press roller. According to the fixing device image defects, including image difference, are less likely to occur when fixing an image on a recording sheet.
