Abstract
On a sliding surface of a heating support body positioned in a downstream side in a film body moving direction wherein the heating temperature is comparatively high and the fluidity of a lubricant agent is good, fluid guiding grooves which uniformly disperse the lubricant agent are provided, thereby well dispersing the lubricant agent over the entire region from a center region to both-end regions of the heating support body and the film body and maintaining good slidability of the film body over a long period of time.
Claims9
A heating device comprising a structure which heats a heating target material pressure-contacted, via a film body, with a sliding surface of a heating support member and a heating surface of a heating body, which is disposed to be exposed in part of the sliding surface of the heating support member, while moving the heating target material together with the film body and
- having an arbitrary lubricant agent interposed between the sliding surface of the heating support member and the heating surface of the heating body and the film body;
- wherein
- a fluid guiding groove approximately uniformly guiding the lubricant agent is provided on the sliding surface of the heating support member;
- and
- the fluid guiding groove is provided in a downstream side of a pressure-bonding part of the film body and the heating target material with respect to a moving direction of the film body.
