<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus in which uneven gloss caused by sheet output means is prevented from occurring to a fixed image formed on a sheet. <P>SOLUTION: An image forming apparatus includes: fixing means for fixing a toner image transferred to a sheet; sheet output means having a set of rollers constituted by a pressing drive roller and a driven roller, and outputting a fixed sheet; and two modes that are a normal sheet-output mode outputting the fixed sheet with the top and bottom surfaces unchanged and an inverted sheet-output mode outputting the sheet with the top and bottom surfaces inverted by the sheet output means. The thermal conductivity of the driven roller is higher than that of the drive roller. In any mode of the two modes, the sheet outputting is performed in a manner so that a sheet surface carrying a fixed toner image is abutted to the driven roller immediately before the sheet reaches the sheet-output roller set. <P>COPYRIGHT: (C)2012,JPO&INPIT |
