Abstract
An object of the present invention is to provide an image heating apparatus for heating an image formed on a recording material that has a heating member, and an excitation coil for generating a magnetic field to induce an eddy current in the heating member, the heating member having a magnetic metallic layer and a non-magnetic metallic layer, the coil being disposed on the magnetic metallic layer side of the heating member.
Claims9
An image heating apparatus for heating an image formed on a recording material, comprising:
- a heating member;
- and
- an excitation coil for generating a magnetic field to induce an eddy current in said heating member;
- said heating member having a magnetic metallic layer and a non-magnetic metallic layer, said coil being disposed on said magnetic layer side of said heating member,
- wherein a length of said magnetic metallic layer in a lengthwise direction is shorter than that of said non-magnetic metallic layer.
A heat generating rotary member for use in an image heating apparatus of an electromagnetic induction type, comprising:
- a magnetic metallic layer;
- and
- a non-magnetic metallic layer provided on an outer side of said magnetic metallic layer,
- wherein a length of said magnetic metallic layer in a lengthwise direction is shorter than that of said non-magnetic metallic layer.
