Abstract: A toner in which mother toner particles containing at least a resin binder and a colorant are coated with an external additive, wherein the mother toner particles contain fine powders of a fluororesin having an average particle size of 1 μm or less in an amount of from 4 to 10 parts by weight, based on 100 parts by weight of the resin binder, and a toner in which mother toner particles containing at least a resin binder and a colorant are coated with an external additive, wherein the external additive contains fine powders of a fluororesin having an average particle size of 1 μm or less in an amount of from 0.3 to 2 parts by weight, based on 100 parts by weight of the mother toner particles. The toner of the present invention is suitably used for, for example, developing a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method, or the like.
