Gloss-imparting device and color image-forming apparatus

A color image forming apparatus comprising:

• a color toner image forming device comprising a photoreceptor and a developing unit that forms a color toner image on the photoreceptor, the color toner image being placed on a recording medium;
• a transparent toner image forming device comprising a photoreceptor and a developing unit that forms a transparent toner image on the photoreceptor, the transparent toner image being placed on the color toner image on the recording medium;
• a fuser comprising a fixing rotatable body and a pressure rotatable body, at least the fixing rotatable body is provided with a heater;
• and
• a cooler located downstream of a nip between the fixing rotatable body and the pressure rotatable body of the fuser in a processing direction of the image formation, the cooler cooling the transparent toner image, color toner image and the recording medium that have been heated and pressurized by the fuser.
