To provide toner for electrostatic image development which highly satisfies low-temperature fixing property, charging characteristics and storage stability as compared with the conventional toner using a crystalline resin and which excels in reliability, a developer for electrostatic image development using the toner, a method for manufacturing the toner for electrostatic image development, and a resin particle dispersion for use in the method.

The toner for electrostatic image development contains a crystalline resin having an ester bond and a sulfide bond and/or a disulfide bond in a backbone.
