Polyurethane member for use in electrophotographic apparatus
摘要:
The invention provides an electrophotography polyurethane member which exhibits small temperature dependency of characteristics, excellent mechanical characteristics, and high wear resistance. The cast-type electrophotography polyurethane member produced through hardening and molding a polyurethane composition containing at least polyol, polyisocyanate, and a diamino compound, wherein the diamino compound has a melting point of 80° C. or lower and contains no chlorine atom but contains an aromatic ring in the molecular structure thereof and exhibits a reaction rate slower than that of 2,2′,3,3′-tetrachloro-4,4′-diaminodiphenylmethane under given hardening and molding conditions.
