Abstract
A heater has a top-surface layer made of an imide-based resin formed on an electrical insulation layer. The heater can generally used for an image heating apparatus incorporated in an image forming apparatus. Since the top-surface layer has preferable sliding and insulating characteristics, the heater provides good heat efficiency and durability.
Claims38
An image heating apparatus comprising:
- a heater for heating an image on a recording material, the heater having a substrate and a heat generating resistor formed on a first plane of said substrate;
- and
- a rotator for rotating in contacting with a second plane opposite to the first plane of said heater, which has a metallic layer,
- wherein a slide layer made of an imide-based resin is formed by coating or screen printing on a surface contacting to an internal surface of said rotator;
- and wherein a thickness of said slide layer is greater than or equal to 3 μm and less than or equal to 10 μm.
