Claim:
1. A toner for electrostatic charge image development comprising: a binder resin, wherein the binder resin comprises the binder resin comprises a phase-separated structure in which the hybrid crystalline polyester resin forms a dispersion phase and the amorphous resin forms a continuous phase, the hybrid crystalline polyester resin is a graft-copolymer having a main chain formed of the amorphous resin unit other than a polyester resin and a side chain formed of the crystalline polyester resin unit, and the toner satisfies the relationships represented by the following formulas (1) and (2): wherein Tm1 (° C.) is the temperature derived from an endothermic peak of the hybrid crystalline polyester resin in the first heating process in a differential scanning calorimetry of the toner; ΔH1 (J/g) is the amount of endothermic heat based on the endothermic peak; and ΔH2 (J/g) is the amount of endothermic heat based on the endothermic peak in the second heating process.
