<p><P>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 durability, and to provide an image forming apparatus. <P>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 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. The second conductive layer is composed of permalloy to which niobium or tantalum is added. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
