A cleaning blade member comprising a polyurethane formed by using a polyol consisting essentially of a polycarbonatediol, a polyisocyanate, and a crosslinking agent containing a short chain diol and a triol, the polyurethane having a tensile strength at 60° C. of 200 kg/cm2 or higher, and a tensile strength retention ΔT, represented by the following equation, of 40% or more: ΔT(%)=T60/T10×100 where T10 denotes a tensile strength at 10° C., and T60 denotes the tensile strength at 60° C.
