    摘要： An image heating device comprises a cylindrical heating roller with a Curie temperature of 210.degree. C., a magnetization coil for magnetizing the heating roller with an alternating magnetic field, which is arranged inside the heating roller, and a nip portion for heating a recording material that carries a toner image with heat from the heating roller, while the recording material is being conveyed along said nip portion. The ratio between the amount of heat generated in said heat-generating member at Curie temperature or higher to the amount of heat generated at room temperature in said heat-generating member is not more than 1/2. With this configuration, the heating roller can regulate its own temperature to stabilize at a temperature that is suitable for fixing, and the problems of partial overheating or underheating, unstable heat generation, or damage of the device can be eliminated.

    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.

    摘要： An oil application roller unit including a holder having at least a shaft or bearings, an oil application roller rotatably supported by the holder, and an oil leakage prevention film closely wound around the oil application roller to pack the roller and capable of being pulled out. By pulling the oil leakage prevention film while the oil application roller remains installed in the holder, the oil application roller is rotated, and the oil leakage prevention film can be removed. Since the user is not required to make contact with the oil application roller at the time of unpacking, the hands of the user are not stained. Unpacking can thus be attained safely.
