Curl caused in a paper sheet in a fixing device during fixing of a toner image is removed while smoothly changing a direction of feed of the paper toward a plurality of paired discharge rollers in the fixing device. Anti-curl ribs, each having a rounded face that projects to pass through a plane connecting a contact point between a heating roller and a pressing roller and a contact point between the respective discharge rollers are arranged between the heating roller and the pressing roller and the plurality of paired discharge rollers in a fixing unit. Further, a first set of paired discharge rollers and a fourth set of paired discharge rollers are arranged respectively in correspondence with the anti-curl ribs and two of the anti-curl ribs are provided in correspondence with the side portions of the paper. Lastly, bent guide films are arranged on both sides of second guide ribs that correspond to the first and fourth sets of paired discharge rollers to facilitate paper feed.
