Abstract
A fixing device includes a flexible endless fixing belt, a heating part, and a belt guide. The heating part induction-heats the fixing belt from outside. The belt guide supports the fixing belt so that the fixing belt faces to the heating part. The belt guide is made of temperature sensitive magnetic material with magnetic characteristics reversibly changing from ferromagnetism to paramagnetism when predetermined temperature is reached, and includes a plurality of slits arranged in a width direction orthogonal to a circumferential direction of the fixing belt and formed along the circumferential direction. At a side of an inner circumference face of the fixing belt, a protecting part is provided so as to prevent the inner circumference face of the fixing belt from coming into direct contact with portions on the periphery of the plurality of slits.
