Abstract
A heating efficiencyincludes a substrateand a plurality of heat generating elementstowhich are provided on both surfaces of the substrateand which generate heat, and heats a fixing belt in contact with an inner peripheral surface of the fixing belt. The plurality of heat generating elementstoare different from each other in length with respect to a widthwise direction, and at least three of the heat generating elements are provided on a front surface of the substratewhich is a side where the heatercontacts the inner peripheral surface of the fixing belt, and at least one of the heat generating elements is provided on a back surface. A longest heat generating element, in length with respect to the widthwise direction, of the plurality of heat generating elements-is provided on the front surface. Further, as regards the heat generating elements-provided on the front surface, with respect to a rotational direction of the fixing belt, the longest heat generating elementin length with respect to the widthwise direction is disposed between the heat generating elementand the heat generating element
