Claims11
An image fixing device comprising:
- a fixing roller including a magnetic metal layer and a non-magnetic metal layer, wherein the nonmagnetic metal layer is provided on an outer side of said magnetic metal layer and is thinner than said magnetic metal layer;
- and
- a coil disposed at a side where the non-magnetic metal layer is provided.
A heat generating rotary member for use in an image heating apparatus of an electromagnetic induction type, comprising:
- a magnetic metal layer;
- and
- a non-magnetic metal layer provided on an outer side of the magnetic metal layer, said non-magnetic metal layer having a thickness smaller than a thickness of the magnetic metal layer.
An image heating apparatus comprising:
- a heating roller including a magnetic metal layer having a first thickness;
- a exciting coil disposed to face said heating roller;
- a belt suspended to be in contact with a part of said heating roller, the part of said heating roller positioned between said heating roller and said exciting coil, and said belt comprising a non-magnetic metal layer thinner than the first thickness.
