    摘要: A heating device includes a magnetic-field generating unit that generates an alternating-current magnetic field, an endless belt, and a heat transfer unit that includes a heat storage layer, a thermosensitive layer, and a diffusion layer. The thermosensitive layer extends so as to separate the magnetic-field generating unit and the heat storage layer from each other, and forms a magnetic path that allows a magnetic flux of the alternating-current magnetic field to pass therethrough in a direction in which the thermosensitive layer extends at a temperature below a Curie temperature and a magnetic path that allows the magnetic flux to extend therethrough and reach the heat storage layer at a temperature higher than or equal to the Curie temperature. The diffusion layer has a higher thermal conductivity than thermal conductivities of the thermosensitive layer and the heat storage layer, and diffusing heat of the belt.

    摘要: A fixing device includes an endless fixing belt which is tensionless in a circumferential direction in a center part in a lateral direction and supported to circularly move, a heating device that heats the fixing belt, a pressure roll contacted with an outer peripheral face and supported to rotate around an axis, a pressure member contacted with an inner peripheral face to exert pressure on the pressure roll, and a support member passed through inside the fixing belt and supporting the pressure member. Preferably, an unfixed toner image on a recording medium passing the nip part which is formed between the fixing belt and the pressure roll is pressurized and heated to be formed into a fixed image, and the fixing belt is kept in a round shape in the circumferential direction near both side edges and supported to rotate around a center axis determined by the support member.
