RESIN MATERIAL, ENDLESS BELT FOR IMAGE FORMING APPARATUS, ROLLER FOR IMAGE FORMING APPARATUS, IMAGE FIXING DEVICE, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a resin material used for a member for an image forming apparatus, which is excellent in both of scratch resistance and quick repair of scratches.

SOLUTION: The resin material used for a member for an image forming apparatus includes: a polymer formed by polymerization of an acrylic resin in which a content ratio (molar ratio) of hydroxyl groups of side chains each containing 10 or more carbon atoms to hydroxyl groups of side chains each containing less than 10 carbon atoms is less than 1/3 (wherein a case in which the acrylic resin does not have hydroxyl groups of side chains each containing 10 or more carbon atoms is included); a polyol that contains a plurality of hydroxyl groups in which all the hydroxyl groups are connected together through a chain containing 6 or more carbon atoms; and an isocyanate, with a polymerization ratio of 0.1 to 10, the polymerization ratio being a ratio (B/A) of a total molar amount (B) of hydroxyl groups contained in all the polyols used for the polymerization to a total molar amount (A) of hydroxyl groups contained in all the acrylic resins used for the polymerization.
