1. A fixing device comprising:
a movable belt;
a planar heat-generating section that is in contact with the belt and in which, among a plurality of heat-generating portions provided in a movement direction of the belt, a heat-generating portion on an upstream side in the movement direction of the belt has a larger heat generation amount than a heat-generating portion on a downstream side; and
a heat pipe that is disposed to be in contact with a surface of the planar heat-generating section opposite to the belt closer to an end portion of the planar heat-generating section than the heat-generating portion on the downstream side in the movement direction of the belt.
