Abstract
A fixing device for fixing an unfixed image on a recording sheet passing through a fixing nip formed by pressing a pressing member against an inside surface of a pressure belt via a low friction sheet, so that an outside surface of the pressure belt presses against a fixing member, wherein the pressing member includes a first pressing part having an elastic front face, and (ii) a second pressing part whose front face presses against a rear face of the first pressing part, the low friction sheet extends from a portion thereof pressed by the front face against the pressure belt, to an upstream end thereof, along a lateral side of the first pressing part, the upstream end being upstream from the other end with respect to a rotation direction of the pressure belt and sandwiched between the rear face and the front face by pressure.
