Patent ID: 7285367

Claim:
A method of manufacturing a toner comprising: a step (A) of forming synthetic resin particles containing a colorant, whose surfaces are covered with a less water-soluble alkaline earth metal salt by mixing a resin kneaded product at least containing the synthetic resin and the colorant and not containing an organic solvent and an aqueous dispersion of the less water-soluble alkaline earth metal salt under heating or under heating and pressurization and cooling them; and a step (B) of removing the less water-soluble alkaline earth metal salt from the surface of the synthetic resin particles containing the colorant, wherein an ionic material that decomposes the less water-soluble alkaline earth metal salt is added to the mixture of the resin kneaded product and the aqueous dispersion of the less water-soluble alkaline earth metal salt in the step (A) wherein the addition amount of the ionic material in the step (A) is from 10% by weight to 50% by weight based on an amount of the ionic material that completely decomposes the less water-soluble alkaline earth metal salt.
