摘要：
An image heating device having a predetermined amount of heat generation with a small electric current. The device has a heat-generating roller having magnetism and conductivity, and an exciting coil opposed to the peripheral face of the heat-generating roller and adapted for allowing the heat-generating roller to generate heat with electromagnetic induction. The exciting coil is composed of a bundle of copper wires extended in the direction of the rotation axis of the heat generating roller. The wires are circumferentially wound along the circumferential direction of the heat-generating roller. The bundled wires are arranged in close contact with each other in the circumferential direction of the heat-generating roller so as to cover the upper half of the heat-generating roller.
