Abstract
An electrostatic charge image developing toner includes toner particles each 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 on a cross section of the toner particle before and after being heated at a temperature of 50° C. and a humidity of 50% RH for three days, a relationship between an area ratio a (%) of the crystalline resin on a cross section with respect to the toner particles before being heated, and an area ratio b (%) of the crystalline resin on the cross section with respect to the toner particles after being heated satisfies Expression (1): 0.9≤a/b≤1.0.
