Abstract:
An image heating device comprising:a heat-generating member comprising a rotatable body having conductivity, and an exciting coil arranged in opposition to the outer peripheral surface of the heat-generating member and adapted for allowing the heat-generating member to generate heat with electromagnetic induction, wherein the exciting coil is composed of a bundle of wires having an insulated surface, which are extended in the direction of the rotation axis of the heat-generating member and circumferentially wound along the circumferential direction of the heat-generating member, and the bundled wires extending in the direction of the rotation axis of the heat-generating member are arranged in close contact with each other in at least one place, and wherein a larger number of bundled wires are superimposed at both ends in a direction away from the heat-generating member than at the central portion in the direction of the rotation axis of the heat-generating member.
