PURPOSE:To prevent an endless belt from meandering by providing a collar that has a larger diameter than the center part of a support roll which is longer than the width of the supported endless belt to the end part of the support roll and a groove inside of it, and bending and fitting the end of the endless belt in the groove. CONSTITUTION:The endless belt 18 is extended between support rolls 16 and 17 and wound around a heat roll 15 by prescribed length. The axial length of the support rolls 16 and 17 is larger than the width of the endless belt 18, diameters of its end parts 16a and 17a are made a little bit larger than the diameter of a heat insulating layer 23, and grooves 16c and 17c are formed inside of them. The end part of the endless belt 18 is bent to form an interlocking part 18a, which is fitted in the grooves 16c and 17c. Consequently, the endless belt 18 is prevented from meandering to fix an image stably on copy paper. |
