Abstract
Official abstract text for this publication.
A fixing device includes: an endless belt member; a secured member disposed to contact the belt member; a support roller that rotatably supports the belt member; a heating unit that heats the belt member; and a rotary pressurizing roller that includes an elastic surface layer that is elastically deformed when the belt member is pressed against the secured member to form a fixing part. The secured member includes a recessed part provided on a surface of the secured member that faces the pressurizing roller and configured to curve the belt member into a recessed shape, projecting parts provided upstream and downstream of the recessed part, respectively, and configured to curve the belt member into a projected shape, and a region provided between at least one of the projecting parts and the recessed part and having a small curvature compared to the corresponding projecting part.
