Abstract
An electrostatic charge image developing toner includes an amorphous polyester resin and a crystalline polyester resin as a binder resin, and by differential scanning calorimetry, which undergoes processes of a first temperature rise, cooling at a rate of −10° C./min and a second temperature rise, an endothermic peak (1) derived from a resin in which at least the amorphous polyester resin and the crystalline polyester resin are compatible is present in the first temperature rise, an exothermic peak having an intensity of 0.1 J/g or more is not present during the first temperature rise, and at least one exothermic peak (2) is present in a temperature range which is lower than that of the endothermic peak (1) by from 5° C. to 15° C. during the second temperature rise.
