Abstract:
A cleaning blade member includes a cleaning layer and an elastic layer provided on the cleaning layer's back surface. Both are formed of a polyurethane member produced through curing and molding a castable polyurethane composition, the cleaning layer containing a long-chain polyol, a polyisocyanate, and a diamino compound having a melting point≦80° C., the elastic layer containing a long-chain polyol, a polyisocyanate, a short-chain diol, and a short-chain triol, and has a percent edge drooping≦7.0%, the cleaning and elastic layers have Young's modulus contribution factors Ra and Rb, respectively. (Rb/Ra)=0.05-6.0. Ra=[TaEa/(Ta+Tb)]. Rb=[TbEb/(Ta+Tb)]. Ea and Eb are Young's modulus of the cleaning and elastic layers, respectively. Ta and Tb represent the thicknesses of the cleaning and elastic layers, respectively, and the overall Young's modulus of the cleaning layer and elastic layer is (Ra+Rb)=5.0-14.0 MPa.
