PURPOSE:To prevent heat loss by keeping both ends of a heat roller covered by bearing members. CONSTITUTION:A bearing member 4 is provided with two opposed grooves 14 on the circular outside circumference thereof and is prevented from rotation by engaging the grooves 14 with a side plate 3. A recess 15 for supporting rotatably a heat roller 1 is provided on one side face of the bearing and an aperture 16 for supporting the end part 2a of a heater 2 or a current conducting member connected thereto is provided to said bearing by penetrating the base thereof to the side face on the opposite side. The shape of the aperture 16 is made to comply with the outside shape of the end part 2a or the current conducting member thereof and is so formed as to prevent the heat loss from the clearance between both. Such bearing member 4 is made of a resin such as polyethylene terephthalate or polyphenylene sulfide. |
