Toner for electrostatic charge image development

A toner for electrostatic charge image development comprising:

• a binder resin, wherein
• the binder resin comprises a hybrid crystalline polyester resin in which a crystalline polyester resin unit and an amorphous resin unit other than a polyester resin are chemically bonded, and an amorphous resin, and comprises a phase-separated structure in which the hybrid crystalline polyester resin forming a dispersion phase and the amorphous resin forming a continuous phase;
• and
• the hybrid crystalline polyester resin is a graft-copolymer having a main chain formed of the amorphous resin unit an other than a polyester resin and a side chain formed of the crystalline polyester resin unit,
• the toner satisfying the relationships represented by the following formulas (1) and (2):
• [Math. 1]
• 0.15<ΔH2/ΔH1≦0.95 (1)
• 55≦Tm1≦80 (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.
