A fixing device (A8A; A8B; A8C; A8D) includes an exciting coil (2A) and a heat-generating rotary member (30; 17; 300; 160). The exciting coil generates a magnetic flux. The heat-generating rotary member performs self-temperature control using a repulsive magnetic flux, and includes a degaussing member (3A-1; 3L), a heat-generating layer (3E), a magnetic shunt alloy layer (3C), and a magnetic flux adjuster (3Q, 3A-1; 3L, 16). The degaussing member generates the repulsive magnetic flux using the magnetic flux generated by the exciting coil. The heat-generating layer generates heat using the magnetic flux generated by the exciting coil. The magnetic shunt alloy layer is disposed between the exciting coil and the degaussing member, and receives heat generated by the heat-generating layer. The magnetic flux adjuster adjusts an amount of the repulsive magnetic flux generated by the degaussing member. |
