Fixer that forms a nip with an induction-heated belt and an image forming apparatus having the same

摘要

A fixer includes a fixing belt configured to move around a center, a heating unit configured to induction-heat the fixing belt, a pressing member that presses an outer surface of the fixing belt, a resilient member disposed opposite to the pressing member across the fixing belt, and a heat generating member that is capable of being induction-heated and disposed along the inner surface of the fixing belt between a first position and a second position that is downstream with respect to the first position in a moving direction of the fixing belt. An upstream end portion of the resilient member in the moving direction is in contact with a third position of the fixing belt, and an angle formed with respect to the center by the second and third positions is equal to or smaller than 60°.
