Abstract:
Provided is a toner for electrostatic image development having low-temperature fixability and providing stability of glossiness for various types of paper. The toner for electrostatic image development includes toner particles having a domain-matrix structure. In the domain-matrix structure, a domain phase including a crystalline polyester resin having a melting point of 40 to 90° C. and a domain phase including a vinyl resin B having a weight average molecular weight of 250,000 to 400,000 are dispersed in a matrix phase including a vinyl resin A having a weight average molecular weight of 10,000 to 50,000.
