PROBLEM TO BE SOLVED: To restrain air flow in a longitudinal direction around a heating means and to avoid the concentration of radiated heat around the heating means. SOLUTION: The air flow generated by a ventilating fan flows into a case member 100 from an aperture 103 and partially flows out from an aperture 108. The other air flow flowing into the member 100 from the aperture 103 flows out from the aperture 109 of the member 100 and flows into a case member 101 from an aperture 110 and then flows out from an aperture 111, whereby an air channel is formed. The air channel is constituted above a fixing roll 61 and a pressure roll 62 by piercing through carrying guides 105 and 107 from the apertures 109 and 110 being the parts of the guides 105 and 107 and passing around a carrying roller 104 and a carrying roll 106 arranged at the apertures 109 and 110 portions.
