Abstract
Disclosed is a toner for electrostatic image development that has excellent low-temperature fixability and also has sufficient heat-resistant storage stability. The toner for electrostatic image development includes toner particles containing an amorphous resin including amorphous resins A and B and a crystalline polyester resin. The toner particles have a domain-matrix structure in which a domain phase including fine core particles of the crystalline polyester resin is dispersed in a matrix phase formed of the amorphous resin A composed of a vinyl-based polymer. The surface of the fine core particles of the crystalline polyester resin is coated with the amorphous resin B composed of a vinyl-based polymer.
