Heating roller, image heating apparatus, and image forming apparatus
InactiveCN1504064AAvoid heatingHeating fastElectrographic process apparatusInduction heating apparatusEddy currentMagnetic flux
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 x10<-5 >Omegam 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.

A method for producing a heat-resisting compound oxide in which oxide particles are made to carry fine particles having a smaller particle diameter than that of said oxide particles. Said oxide particles or their precursor particles are charged to a potential inverse to that of said fine particles or their precursor particles so that said oxide particles adsorb said fine particles, and are then sintered to carry said fine particles. Thus, the fine particles can be homogeneously dispersed and firmly adhered to the surfaces of the oxide particles. As a result, the compound oxide is so excellent in heat resistance that it has little change, even subjected to a treatment such as a sintering, in the structure of the oxide particles for a carrier or in the adsorption state of the ultrafine particles, and has little thermal deterioration.
