Abstract: A heating device suppresses 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. The sliding friction resistance in the rotation axis direction of a fixing film between the fixing film and a protrusion is set so that at least the sliding friction resistance in an end part in the rotation axis direction is larger than the sliding friction resistance in a region closer to a central part in the rotation axis direction than the end part.
