A cleaning blade for use in an electrophotographic apparatus, which rubs and eliminates residual toners. The cleaning blade is made up of polyrethane resin sheet controls chipping of a top end of the cleaning blade and reduces an abrasion of a photosensitive drum. The cleaning blade is prepared by mixing and hardening at least a prepolymer, which is obtained from butylene adipate polyester polyol, hexylene adipate polyester polyol and polyisocyanate, and a hardening agent including a low molecular weight polyol and potassium acetate so that a mol ration (&agr; value) of hydroxyl group to isocyanate group becomes not less than 0.7 and not more than 0.9.
