<p>An image heating device having a predetermined heat generation rate with a low current. The device comprises a heating roller (1) having magnetism and conductivity, an exciting coil (5) opposed to the peripheral face of the heating roller (1) and adapted for allowing the heating roller (1) to produce heat with electromagnetic induction. The exciting coil (5) is composed of a bundle of sixty copper wires of a 0.2 mm diameter are extended toward the rotary shaft of the heating roller (1) and they are circumferentially wound along the circumferential direction of the heating roller (1). The bundled wires are arranged in close contact to each other in the circumferentially direction of the heating roller (1) so as to cover the upper half of the heating roller (1).</p> |
