Abstract:
1. A resin material used for a member for an image forming apparatus, the resin material comprising: a polymer, wherein the polymer is formed by polymerization of at least one 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 (the acrylic resin may contain no hydroxyl group of a side chain containing 10 or more carbon atoms); at least one polyol that contains a plurality of hydroxyl groups in which all the plurality of hydroxyl groups are connected together through a chain containing 6 or more carbon atoms; and an isocyanate, with a polymerization ratio of about 0.1 or more and about 10 or less, 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.
