Abstract
An electrostatic charge image developing toner includes toner particles including an amorphous resin and a crystalline resin, wherein, when the toner particles are subjected to a measurement by differential scanning calorimetry before and after being heated at a temperature of 50° C. and a humidity of 50% RH for a week, a relationship between an endothermic amount x (J/g) derived from the crystalline resin with respect to the toner particles before being heated and an endothermic amount y (J/g) derived from the crystalline resin with respect to the toner particles after being heated satisfies Expression (1): x/y<0.3.
