Abstract
An image heating apparatus has an excitation coil for generating a magnetic field and a heating member for dissipating heat by an eddy current induced in the heating member by that magnetic field. A core is provided for guiding the magnetic field and the core includes a sheet-shaped multi-layered magnetic member and is held by a holder which includes a cramping portion to cramp the core with the cramping portion.
Claims9
An image heating apparatus for heating an image formed on a recording material, comprising:
- an excitation coil for generating a magnetic field by being energized;
- a heating member for dissipating heat by an eddy current induced in the heating member by the magnetic field;
- a core for guiding the magnetic field, said core including a sheet-shaped multi-layered magnetic member;
- and
- a holder made of resin, for holding said core and said excitation coil,
- wherein said holder includes a cramping portion for cramping said core with an elastic force.
