摘要： Provided is a toner for electrostatic image development, having low-temperature fixability and long-term stable charge property and also having heat-resistant storage stability. The toner for electrostatic image development includes toner particles containing a binder resin. The binder resin has a domain-matrix structure in which a crystalline polyester resin is dispersed as a domain phase in a matrix phase formed of an amorphous vinyl polymer formed using at least a vinyl-based monomer. The amorphous vinyl polymer has a carboxy group concentration of not less than 0.2 mmol/g and not more than 1.0 mmol/g, and the crystalline polyester resin has an ester group concentration of not less than 0.1 mmol/g and not more than 7.1 mmol/g.

摘要： 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.
