Claim Text:
1. A sliding member for sheet-shaped recording material detachment comprising: as a first element, a resin composite containing either an adhesive fluorocarbon resin (A) or a resin compound of the resin (A) and a fluorocarbon resin (B) which differs from the resin (A), which are in a volumetric ratio (AB) of 5/95 to 99/1; and as a second element, 0.5 to 99 volume % of a thermoplastic polyimide (C), wherein the adhesive fluorocarbon resin (A) is a fluorine containing copolymer containing a first repeating unit based on tetrafluoroethylene, a second repeating unit based on a cyclic hydrocarbon monomer having a dicarboxylic anhydride group and a polymerizable unsaturated group in a ring, and a third repeating unit based on another monomer, and the first repeating unit is 50 to 99.89 mol %, the second repeating unit is 0.01 to 5 mol %, and the third repeating unit is 0.1 to 49.99 mol % based on a total molar amount of the first repeating unit, the second repeating unit, and the third repeating unit, the fluorine containing copolymer has compatibility with the thermoplastic polyimide (C), and the sliding member is an injection molded article of a molten and kneaded mixture of the resin composite.
