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.
A toner in which mother toner particles comprising at least a resin binder and a colorant are coated with an external additive, wherein the external additive comprises 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, fine inorganic particles A having an average particle size of from 5 to 100 nm and fine inorganic particles B having an average particle size of from 5 to 100 nm and which is smaller than the average particle size of the fine inorganic particles A, and
