Abstract: The blade member is formed of a polyurethane member produced through curing and molding a castable polyurethane composition containing at least a polyol, an isocyanate compound, and a cross-linking agent. The polyurethane member exhibits a storage modulus (1 Hz) as measured at 40° C. of 2.0×107 Pa or higher and a (G′10)/(G′50) of 3 or lower, wherein represents a storage modulus (1 Hz) as measured at 10° C. (Pa) and G′50 represents a storage modulus (1 Hz) as measured at 50° C. (Pa).

Abstract: The present invention provides a cleaning blade member which can be excellently produced by molding and which exhibits small variation in physical properties with temperature, and excellent wear resistance. The cleaning blade member formed of a castable polyurethane member produced through hardening and molding a polyurethane composition containing at least a polyol, a polyisocyanate, and a diamino compound, wherein the diamino compound has a melting point of 80° C. or lower, the polyisocyanate is a blend of 4,4′-diphenylmethane diisocyanate (MDI) and 3,3-dimethylphenyl-4,4-diisocyanate (TODI), and the ratio of TODI in the entirety of polyisocyanate is 30 to 100% by weight.
