Patent abstract
A process for producing a polymerized toner, which comprises steps of forming an aqueous dispersion comprising the colored polymer particles, subjecting the aqueous dispersion comprising the colored polymer particles to stripping treatment in the presence of a nonionic surfactant, dehydrating and washing the aqueous dispersion, wherein washing is carried out by using a washing water a temperature of which is controlled to lower than the cloud point of the nonionic surfactant, drying the wet colored polymer particles, and then getting the colored polymer particles.
