Summary:A black toner for developing a latent electrostatic image, including: a toner base containing a pigment, a binder resin, a releasing agent, a compound containing fluorine and a compound containing sulfur; and an external additive, wherein the toner contains the external additive on a surface of the toner base, and wherein an amount of the fluorine in the toner base is 200 ppm by mass to 600 ppm by mass as measured by combustion-ion chromatography, and an amount of the sulfur in the toner base is 1,000 ppm by mass to 1,500 ppm by mass as measured by the combustion-ion chromatography.
