Document Type and Number:
Japanese Patent JP3972842
Kind Code:
B2
Abstract:
In a method for manufacturing a polymerized toner, in a washing step after polymerization, colored polymer particles are washed using a continuous pressurizing filter in a circulation washing manner, in which a dispersion containing colored polymer particles obtained in the polymerization step is supplied by pressure to the inlet of the continuous pressurizing filter from a slurry tank that stores the dispersion; the dispersion is filtered in the filter while stirring; the concentrated dispersion is fed back to the slurry tank from the outlet; a washing solution in a quantity equivalent to the quantity of the filtrate filtered by filtration is added to the slurry tank to dilute the filtrate; and the dispersion diluted by the washing solution is circulated in the filter.
