PROBLEM TO BE SOLVED: To obtain a film for a pressure roller which requires no adhesive layer and maintains or improves properties obtained heretofore, such as excellent releasability from a recording material as well as tensile strength and tear strength. SOLUTION: The film for a pressure roller has a polyimide layer in which a fluorocarbon resin powder has been dispersed. Particularly, 10-20 vol.% of the fluorocarbon resin powder has been dispersed in the polyimide layer and an average particle diameter of the powder is 1-20μm. COPYRIGHT: (C)2006,JPO&NCIPI |
