Abstract:
Provided is a toner for electrostatic image development that has good low-temperature fixability, also has long-term heat-resistant storage stability and can form an image with unevenness in gloss suppressed. The toner for electrostatic image development includes toner particles. The toner particles have a domain-matrix structure in which a first domain phase including a crystalline polyester resin A and a second domain phase including a crystalline polyester resin B are dispersed in a matrix phase including a vinyl resin. The average diameter of the first domain phase is 400 to 900 nm, and the average diameter of the second domain phase is 10 to 200 nm. The melting point of the crystalline polyester resin A and the melting point of the crystalline polyester resin B are each 95° C. or lower.
