Abstract
An electrostatic image developing toner includes a toner particle and an external additive. The toner particle contains a binder resin and a release agent that includes a hydrocarbon wax. The binder resin includes a vinyl resin and a hybrid resin in which an amorphous resin unit other than polyester resins and a crystalline polyester resin unit are chemically bound together. The toner particle has hybrid resin domains and release agent domains. An average distance Lhyb from the surface of the toner particle to the centers of the hybrid resin domains and an average distance Lwax from the surface of the toner particle to the centers of the release agent domains satisfy Lwax<Lhyb.
