PROBLEM TO BE SOLVED: To provide a heating apparatus 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.SOLUTION: 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. |
