ABSTRACT:
An image forming apparatus includes: a first image forming unit which forms a first image on a first recording medium with a first material which is not thermally decolorized; a second image forming unit which forms a second image on a second recording medium with a second material which is thermally decolorized; a fixing unit which is on a common carrying path shared by the first recording medium and the second recording medium and fixes the first image to the first recording medium; and a control unit which controls the fixing unit so that the temperature of the second recording medium passing through the fixing unit becomes lower than a decolorizing temperature of the second material.
