Abstract:
A heating rotator that is used for heating a developer on a recording medium has a cylindrical body that is made of a metal and both end portions of the cylindrical body is rotatably supported. The cylindrical body has a thick-walled portion at both end portions that is thicker than a center portion in an axial direction of the cylindrical body, and a cross-sectional shape of the heating rotator changes from the end portions toward the center portion in a pressure area of an outer peripheral surface to which pressure is applied by a pressure rotator.
