This heating apparatus has the thickness of the induction coil in the range of 0.2-0.8 mm. The gap between the induction coil and the conductive member is in the range of 0.5-4.0 mm. This heating apparatus has the induction coil thrust out of the conductive member. The induction coil is formed of a Litz wire.

摘要： An induction heating device for printers, copiers and the like includes a magnetic coil assembly and a heated metal body that form a closed magnetic circuit. To compensate for the effects of heat radiation at the ends of the heated metal body, a greater amount of heat is generated at the ends of the body than at the center thereof. In one approach, the amount of heat is varied by changing physical parameters of the magnetic circuit, such as the spacing of the coil assemblies from the heated body, the relative sizes of the cores, and/or the relative magnetic permeability of the cores. In another approach, the electrical connection of the coils of multiple assemblies are arranged such that the coils in the center of the heated body are in parallel, and the coils at the ends of the body are in series with the parallel central coils.

摘要： A toner image formed on a recording member is fixed onto the recording member by a fixing device having a heatable member, a heater for heating the heatable member positioned on one side of the heatable member, the recording member being positioned on an opposite side of the heatable member and spaced from the heatable member to heat the recording member by radiation from the heatable member, and a fixing structure for fixing the toner image on the heated recording member. The heatable member can be a fixing belt arranged in a loop while the heater is an electromagnetic induction coil positioned substantially within the loop. The electromagnetic induction coil generates a magnetic flux perpendicular to the transport direction of the fixing belt to produce an eddy-like induction current in a conductive member of the fixing belt to heat the fixing belt. The fixing belt, in turn, heats the recording member on the exterior side of the belt to soften the toner image thereon. The fixing structure, e.g., a pressure roller, then fixes the toner image on the heated recording member. The heatable member may be a conductive guide member, or a belt arranged in a loop and having a tension roller with the electromagnetic induction coil being arranged on an interior side of the tension roller.
