Abstract:
1. A process for producing toner particles, in which a polymerizable monomer or a polymerizable monomer composition containing at least a polymerizable monomer is polymerized in an aqueous medium in a vessel to produce toner particles, the process comprising the steps of: kneading a mixture containing at least a THF-insoluble resin component other than desired toner particles generated in the process for producing the toner particles to reduce an amount of the THF-insoluble resin component in the mixture thereby generating a kneaded material with reduced THF-insoluble resin component; pulverizing the kneaded material to obtain powder of the kneaded material; and adding the powder of the kneaded material into a polymerizable monomer or a polymerizable monomer composition containing at least a polymerizable monomer.
