Abstract:
An example image forming apparatus includes an image forming unit to form a toner image on a print medium by using an electrophotographic method, a fixing unit to fix the toner image to the print medium by heat and pressure, a photo finishing unit to apply heat and pressure to the print medium after fixing and to cool the print medium, and a clear toner application unit located on an upstream side of the photo finishing unit with respect to a transporting direction of the print medium to apply 0.3 mg/cm2 or more of a clear toner to the print medium.
