An object of the present invention is to provide a toner for developing an electrostatic charge image, which is excellent in prolonging the life of a photoreceptor, fixing property, cleaning property, environment resistance, adhesion resistance, and heat-resistant storage stability and obtaining a high-quality image. A toner base particle comprising core particles containing a binder resin, a release agent and a colorant, and convex portions formed by resin fine particles on the surface of the core particles, and an external additive. The toner for developing an electrostatic charge image, wherein the external additive is inorganic fine particles, the binder resin contains a crystalline polyester resin and an amorphous polyester resin, and 1 mg / mg of the toner for developing an electrostatic charge image. Before irradiating 20 mL, 80 W / 10 cm 2 ultrasonic waves to the mL dispersion, the particle size measured by a flow-type particle image analyzer for 1 minute irradiation, 5 minute irradiation, and 10 minute irradiation is 0.6 μm to When the abundance ratio (number%) of particles having a diameter of 2.0 μm is Z, A, B, and C, 0 ≦ AZ ≦ 3.0, 0.5 ≦ BZ ≦ 4.0, and An electrostatic charge image developing toner satisfying 4.0 ≦ C−Z ≦ 8.0.
