Abstract: A fixing device includes a cylindrical heat roller, a heating element, a pressure roller, and an auxiliary roller. The heating element is provided inside the heat roller and configured to apply heat to the heat roller. The pressure roller is configured to be pressed against the heat roller to form, with the heat roller, a nip area where a recording paper sheet is to be nipped. The auxiliary roller is provided inside the heat roller and configured to be pressed toward the pressure roller with a peripheral wall of the heat roller in between. An outer peripheral surface of the auxiliary roller pressed against an inner peripheral surface of the heat roller is formed into an inverted crown shape so that an outside diameter of the auxiliary roller gradually decreases from both axial ends of the auxiliary roller toward an axial center thereof.

Abstract: A heat roller includes a main body and a follower gear. The main body includes a cutaway portion and a pair of protruding plate portions. The follower gear includes a transmission protrusion and an abutment portion. The transmission protrusion is abutted against one protruding plate portion, when the follower gear rotates. The abutment portion is abutted against the one protruding plate portion, when the main body rotates in advance. A size of the transmission protrusion along the width direction of the cutaway portion is smaller than a clearance between the pair of protruding plate portions in the width direction, and a clearance between the abutment portion and the one protruding plate portion in the roller rotation direction is narrower than a clearance between the transmission protrusion and the other protruding plate portion in the roller rotation direction, when the transmission protrusion is in contact with the one protruding plate portion.

Abstract: A fixing device includes a rotatable cylindrical heating roller, a heat source and a pressing roller. The heat source is arranged in a hollow inner space of the heating roller. The pressing roller is pressed against the heating roller to form a fixing nip through which a sheet is passed in a sheet passing direction. The heating roller has a substrate layer and a heat conductive layer. The substrate layer is formed such that both end portions in a width direction perpendicular to the sheet passing direction are made thinner than a center portion in the width direction, within a sheet passing area through which the sheet is passed. The heat conductive layer is provided around an outer circumferential face of the substrate layer and has a heat conductivity higher than the substrate layer.
