A toner for electrostatic image development which, even when it employs a binder resin comprising an alicyclic olefin resin, causes neither an offset phenomenon nor a winding phenomenon during fixing in a wide temperature rang e, i.e., is excellent in fixing characteristics at high temperatures and in unsusceptibility to fusion bonding. The toner for electrostatic image development comprises two or more binder resins and a colorant, wherein the binder resins comprise an alicyclic olefin resin (A) and a thermoplastic elastomer (B). The alicyclic olefin resin (A) preferably is a copolymer comprising structural units of a cycloolefin (A1) and structural units of a noncyclic unsaturated monomer (A2). The thermoplastic elastomer (B) preferab ly has a melting point of 60 to 190~C.
