Provided is a heating device capable of suppressing a bias force toward a center in a longitudinal direction (center in a rotation axis direction) of a fixing film serving as a rotation member, thereby preventing film overlapping and sheet wrinkles. A sliding friction resistance in the rotation axis direction of a fixing film (118b) between the fixing film (118b) and a protrusion (118g) is set so that at least a sliding friction resistance in an end part in the rotation axis direction is larger than a sliding friction resistance in a region closer to a central part in the rotation axis direction than the end part. |
