(57) [Abstract] [Problem] Excellent transferability and cleaning property. An object of the present invention is to provide an electrostatic charge image developing toner having excellent durability of a large number of sheets with less deterioration of external additives. SOLUTION: (a) Toner particles having a weight average particle diameter of 1 to 9 μm, (b) Hydrophobicized inorganic fine powder having an average particle diameter of 10 to 90 nm, and (c) Hydrophobicized silicon compound fine powder. Is a toner for developing an electrostatic charge image, and the hydrophobicized silicon compound fine powder has an average particle size of 30 to 1 20 nm, containing 15 to 45% by number of silicon compound particles having a particle size of 5 to 30 nm, containing 30 to 70% by number of silicon compound particles having a particle size of 30 to 60 nm, and having a particle size of 60 nm A toner for developing an electrostatic charge image, characterized by containing 5 to 45% by number of the above silicon compound particles. |
