ABSTRACT:
A method of manufacturing a toner for developing static charges in an aqueous system is provided which includes preparation step for a resin kneaded product, preparation step for the aqueous dispersion of a less water-soluble alkaline earth metal salt, preparation step for synthetic resin particles, removal step for the less water-soluble alkaline earth metal salt, and separation-cleaning-drying step. At preparation step S3for synthetic resin, an ionic material for decomposing the less water-soluble alkaline earth metal salt is admixed with a mixture of the resin kneaded product and the aqueous dispersion of the less water-soluble alkaline earth metal salt.
