Abstract:
1. A fixing device comprising: a fixing member for fixing a transferred toner image onto a transfer target through a heating process; and a pressing member disposed in contact with said fixing member to define therebetween a nip zone for passing the transfer target therethrough, wherein said fixing member includes: wherein: said temperature-sensitive metal layer is disposed closer to said induction coil than said nonmagnetic metal layer; said nonmagnetic metal layer is made of a metal having a specific resistance value less than that of aluminum, and formed to have a thickness allowing said nonmagnetic metal layer to be substantially free from a temperature rise due to said induction heating; and said metal having a specific resistance value less than that of aluminum is copper, wherein a lower limit value of the thickness of said nonmagnetic metal layer is set at 30 μm.
