Electrostatic image developing toner, electrostatic latent image developer, and toner cartridge

An electrostatic image developing toner comprising:

• a toner particle;
• and
• an external additive, the toner particle containing a binder resin and a release agent that includes a hydrocarbon wax, the binder resin including 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,
• wherein the toner particle has hybrid resin domains and release agent domains,
• an average area fraction of the release agent domains present in a region extending from a center of the toner particle toward a surface of the toner particle by half a distance from the surface to the center is larger than an average area fraction of the hybrid resin domains present in the region, and
• an average area fraction of the release agent domains present in a region extending from the surface of the toner particle toward the center of the toner particle by half the distance from the surface to the center is smaller than an average area fraction of the hybrid resin domains present in the region.
