Abstract
A fixing device includes an endless belt member, a secured member disposed to contact the belt member, a heating unit that heats the belt member, and a rotary pressurizing roller including an elastic layer that is elastically deformed when the belt member is pressed against a pressing surface of the secured member to form a fixing part. The pressurizing roller is curved such that a center portion is smaller in outside diameter than end portions along the axial direction. The pressing surface is curved such that a center portion projects toward the pressurizing roller more than end portions along the longitudinal direction. On the pressing surface, an amount of projection of the center portion with respect to the end portions along the longitudinal direction is set to be larger on an output side than on an input side of the fixing part along a moving direction of the belt member.
