Zusammenfassung:PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner having excellent electrification characteristics, causing little contamination of a photoreceptor drum, thereby forming an image of high picture quality with little nonuniformity in density, and suppressing the amount of consumption of the toner. SOLUTION: The electrostatic charge image developing toner consists of toner particles containing at least a resin and a coloring agent, and contains fine particles of a calcium phosphate compound having 0.3 to 3.0 μm average particle size and depositing on the surface of the toner particles.
