    • A fixing apparatus 50 capable of reducing noise during a fixing operation using a fixing belt 1 having a metal layer includes the fixing belt 1 stretched between a fixation roller 2 and a fixation tension roller 3. The fixing apparatus 50 further includes a coil 4b which is disposed opposite from the fixation tension roller 3 via the fixing belt 1 and is supplied with an AC (600 V, 25 kHz at maximum) by an IH controller 10, so that the fixing belt 1 and the fixation tension roller 3 are simultaneously heated by induction heating. In the fixing apparatus 50, insulating belt flanges 25a and 25b are attached to the fixation tension roller 3 at both end portions of the fixation tension roller 3 to limit movement of the fixing belt 1 in a width direction of the fixing belt 1.
    • 能够使用具有金属层的定影带1在定影操作期间减少噪音的定影装置50包括在定影辊2和定影张紧辊3之间拉伸的定影带1.定影装置50还包括线圈4b, 经由定影带1与定影张紧辊3相对设置,并且通过IH控制器10向AC(600V,最大为25kHz)供应,使得定影带1和固定张力辊3同时被 感应加热。 在定影装置50中,绝缘带凸缘25a和25b在定影张紧辊3的两端附接到定影张紧辊3,以限制定影带1在定影带1的宽度方向上的移动。
