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 to determine an area ratio of the crystalline resin present on a surface of the toner particle before and after being heated at a temperature of 50° C. and a humidity of 50% RH for a week, a relationship between an area ratio a (%) of the crystalline resin present on a surface of the toner particles before being heated and an area ratio b (%) of the crystalline resin present on a surface of the toner particles after being heated satisfies Expression (1): 0.05≤(b−a)/b≤0.50.
