Roller, the manufacturing method of the heat fixing apparatus and an electrophotographic roller with this

摘要

PROBLEM TO BE SOLVED: To provide a roller in which adhesive strength between an intermediate layer and a surface layer is high, which prevents holes, roughness, cracks and contamination from occuring in the surface layer, has the uniform and smooth surface layer and is excellent in durability (though durable, toner adhesion is eliminated). SOLUTION: The roll composed of at least a core bar, an elastic layer, an intermediate layer and a surface layer is constituted by manufacturing the intermediate layer and the surface layer by applying a coating material containing a fluororesin and dispersing an inorganic filler in the intermediate layer.
