Induction heating type image heating apparatus |
摘要 |
An image heating apparatus for heating an image formed on a recording material includes a heating member having a heat-generating layer, and magnetic field-generating means for generating a magnetic field to induce an eddy current in the heat-generating layer. The magnetic field-generating means includes a core and a coil disposed around the core in a longitudinal direction of the core. When the coil has a minimum length L1 and a maximum length L2 respectively in a longitudinal direction thereof; the core has a maximum length Lc in the longitudinal direction thereof; the core and the heating layer form a gap d therebetween; and the recording material has a prescribed maximum size giving a passing width Lp; these values satisfying the following relationship:
