Zusammenfassung:An electrostatic charge image developing toner that contains toner particles containing a binder resin containing an amorphous resin and a crystalline resin, and satisfying the following condition (1) and condition (2),condition (1): in a case where differential scanning calorimetry is performed by the following thermal process (1), a total amount of heat generated at an exothermic peak in a temperature range of 30° C. or higher and 70° C. or lower during a reheating period is more than 0.5 J/g,condition (2): in a case where differential scanning calorimetry is performed by the following thermal process (2), a total amount of heat generated at an exothermic peak in a temperature range of 30° C. or higher and 70° C. or lower during a reheating period is 0.5 J/g or less,thermal process (1): heating to 150° C. from 0° C. at a rate of 10° C./min, then cooling to 0° C. from 150° C. at a rate of 50° C./min, followed by reheating to 150° C. from 0° C. at a rate of 10° C./min,thermal process (2): heating to 150° C. from 0° C. at a rate of 10° C./min, then cooling to 0° C. from 150° C. at a rate of 1° C./min, followed by reheating to 150° C. from 0° C. at a rate of 10° C./min.
