PURPOSE:To provide a titled device which has good thermal efficiency and has a small size, by mixing inorg. fibers and a heat resistant resin material, forming a preventive member for heat radiation of the mixture thereof, and forming the surface on a rotating body side of a metallic surface having heat reflectivity. CONSTITUTION:A preventive member 8 for heat radiation and a thin metallic surface layer 7 have respectively the length covering the entire part of a heating roll in the axial direction thereof and the width covering the part between a cleaning position where there is a pressing roll 63 and the entrance part for paper P. The width is so determined as to cover the roll 1 as much as possible. On the other hand, a perventive member 10 for heat radiation having the similar constitution as the constitution of the member 8 is provided apart at a prescribed distance l2 from the peripheral surface of a pressing roll 2 so as to cover the greater part thereof. The member 10 has a reflective thin metallic surface layer 9 at roughly a uniform thickness over the entire side face on the peripheral surface side of the pressing roll. The fixing of the member 10 is accomplished by means of screws 31 without contact with the layer 9. |
