An inorganic fine particle for a toner for developing an electrostatic image, which is excellent in chargeability, charge rising property, toner spent property, fluidity, ground stain resistance, offset resistance, environmental preservation property, in-machine scattering property, and the like of a toner. Provided are a toner in which the fine particles are mixed, a developer containing the toner, an image forming apparatus loaded with the toner, and an image forming method using the toner. An inorganic fine particle having an average primary particle diameter of 1 to 200 nm, which is surface-treated with at least both a fluorine-containing compound and a silicon-containing compound, for use in a toner for developing an electrostatic image. Inorganic fine particles. A toner for developing electrostatic images, wherein at least the above-mentioned inorganic fine particles are mixed in a toner containing at least a colorant and a resin.
