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： The fixing device includes: a fixing member that includes a conductive layer capable of heating by electromagnetic induction; a magnetic field generating member that generates an alternate-current magnetic field intersecting with the conductive layer of the fixing member; plural magnetic path forming members that form a magnetic path of the alternate-current magnetic field generated by the magnetic field generating member; a support member that supports the magnetic field generating member; an elastic support member that is arranged between the magnetic field generating member and the plural magnetic path forming members so as to be in contact with the plural magnetic path forming members; and a pressing member that presses the plural magnetic path forming members toward the magnetic field generating member.
