公开了一种用于加热的带用于输送是未定影的图像形成被固定到通过加热介质抑制在加热元件和该绝缘层的剥离介质中的加热装置。 的加热单元58，该金属层581包括：从在该顺序在定影带51的内周面堆积的绝缘层582，金属层583，绝缘层584，金属层585，朝向轴线O1。 该金属层581（加热区）的一些区域是由发热金属层583的加热。 金属层581585，绝缘层582，584及金属层583，在比所述加热区域中，热塑性粘合剂等地区，被串联连接在金属层581和金属层585的法线方向。 .The

To provide a heating apparatus for heating a belt for conveying the medium that is unfixed image formation is fixed on the medium by heating, suppressing the peeling of the heating element and the insulating layer.
A heating unit 58, the metal layer 581 includes stacked insulating layer 582, metal layer 583, the insulating layer 584, a metal layer 585, towards the axis O1 of the inner circumferential surface of the fixing belt 51 in this order. Some areas of the metal layer 581 (heating region) is heated by heat generation of the metal layer 583. Metal layers 581,585, insulating layer 582, 584 and the metal layer 583, in regions other than the heated region, with a thermoplastic adhesive, which is connected in the normal direction of the metal layer 581 and the metal layer 585.
