An electrostatic charge image developing toner includes toner particles; and an external additive that is externally added to surfaces of the toner particles, in which a content of nitrogen atoms on the surfaces of the toner particles is from 0.8 atomic % to 5.0 atomic % and a content of nitrogen atoms at a depth of 10 nm inside from the surfaces of the toner particles is 0.4 atomic % or less when measured by X-ray photoelectron spectroscopy.
