Production apparatus of toner for developing electrostatic images, production method thereof, and toner for developing electrostatic images

摘要

An apparatus for producing toner for developing an electrostatic latent image, is provided with an inlet section to receive a slurry containing toner particles, impure fine particles having a specific gravity smaller than that of the toner particles and aqueous medium; a centrifugal concentrating device for applying centrifugal force to the slurry and having a precipitating plate with which the toner particles are precipitated from the slurry and an accommodating section to accommodate a concentrated slurry containing the precipitated toner particles, and an outlet section to deliver impure fine particles and aqueous medium.
