摘要： A fixing device enabling the temperature of a heating element to be uniformly and stably maintained even if the heating element is eccentrically moved or vibrated. An opposed core (233) is so formed that a small diameter opposed core (2332) is fixedly inserted onto the center part of a core shaft (2331) and large diameter opposed cores (2333) are fixedly inserted onto both end parts of the core shaft (2331) so that the cross sectional area thereof at both ends in the lateral direction (both ends in the longitudinal direction) is larger than the cross sectional area thereof at the center part in the lateral direction. A fixing belt (210) is formed of a non-magnetic material and disposed between a core (232) and the opposed core (233). Thus, since a magnetic flux between the core (232) and the opposed core (233) is not almost varied and the fixing belt (210) allows the magnetic flux to pass therethrough and does not affect the flux, even if the fixing belt (210) is rotated and a distance between the core (232) and the fixing belt (210) is varied, the temperature of the fixing belt (210) can be uniformly and stably maintained.

摘要： There is provided a fixing apparatus capable of reducing the warm-up time, improving the heating efficiency, and suppressing the temperature increase out of the sheet width by using a magnetic adjuster. In this apparatus, the Currie temperature Tc of the magnetic adjuster material heated by electromagnetic induction is set to 220 degrees C. or below and the fixation setting temperature of a heating member corresponding to the portion where a recording material passes during continuous sheet feed is set lower than a value than the temperature at which the relative magnetic permeability of the magnetic adjuster material begins to decrease. Thus, it is possible to obtain a large difference between the heating portion and the non-heating portion, to surely prevent excessive temperature increase of the portion out of the recording material width, to reduce the warm-up time, and improve the heating efficiency.

摘要： A heating roller (21) includes a heat generating layer (22) that generates heat by electromagnetic induction, a heat insulating layer (23), and a supporting layer (24), which are provided inwardly in this order. The supporting layer (24) is formed of a material having a specific resistance of 1×10−5 Ωm or higher. Therefore, even when the heat generating layer (22) has a thickness smaller than a skin depth, i.e. a thickness defined by a flow of an induction current, so that magnetic flux penetrates the heat generating layer (22) and even reaches the supporting layer (24), heat generation of the supporting layer (24) under an eddy current can be suppressed. Thus, the heat generating layer (22) can be decreased in thermal capacity, and heat generation of the supporting layer (24) is suppressed, so that only the heat generating layer (22) can be heated efficiently. As a result, a warm-up time can be reduced. Further, breakage by heat of, for example, bearings supporting the heating roller (21) can be prevented.
