发明名称 FIXING DEVICE AND IMAGE FORMING APPARATUS
摘要 PROBLEM TO BE SOLVED: To provide a fixing device which does not cause partial excessive temperature rise even when small-size paper is made to pass continuously, which has stable fixing performance and which is excellent in heat generation efficiency, and to provide an image forming apparatus. SOLUTION: The fixing device 1 includes a heating roller 11, a pressure roller 12 and a magnetic flux generation part 13 applying magnetic flux to the heating roller 11. The heating roller 11 is a rotating body which includes a first conductive layer (main heating element layer 24), a second conductive layer (heat generation control layer 23) and a third conductive layer (core bar 21) in order from a side nearer to the magnetic flux generation part 13, wherein the first conductive layer is formed of a non-magnetic substance and has≤40μm thickness, and the first conductive layer and the second conductive layer are integrated by cladding.
