1. A method of cleaning a fixing apparatus comprising a heating member which is formed into a cylindrical shape and having an outer peripheral surface heated at a predetermined temperature; and a pressurizing member which contacts the heating member under a predetermined pressure; the method comprising: supporting one end of a cleaning sheet on an upstream side of the heating member in a rotation direction of the heating member; supporting the other end of the cleaning sheet on a downstream side of the heating member in the rotation direction; and pressing the cleaning sheet against the heating member at positions apart from each other in the rotating direction in such a manner that a load applied on the cleaning sheet at a position on the downstream side is smaller than that applied on the cleaning sheet at the other position on the upstream side of the heating member in the rotation direction.
