摘要： A toner for producing electrostatic latent images is produced by classifying a pulverized feed material into a coarse powder and a fine powder in a first classifying means, pulverizing and recycling the coarse powder to the first classifying means, introducing the fine powder into a multi-division classifying chamber divided into at least three sections where the fine powder is classified into at least a coarse powder fraction, a medium powder fraction and a fine powder fraction. The medium powder fraction is recovered to provide a toner. The coarse powder fraction is recycled to the first classifying means.

摘要： A process for producing a toner has the steps of, polymerizing a polymerizable monomer composition containing at least a polymerizable monomer and a colorant, in an aqueous dispersion medium to form colored polymer particles, and thereafter washing the colored polymer particles, followed by dewatering to prepare wet colored polymer particles, subjecting the resultant wet colored polymer particles to substantial removal of the water held by the wet colored polymer particles, by means of a dryer making use of hot air to obtain toner particles, and drying the toner particles under reduced pressure by means of a vacuum dryer so that polymerizable monomers remaining in the toner particles come to be in a residue of 200 ppm or less.

摘要： A process for classifying toner particles supplied through a supply nozzle into at least three fractions in a classifying chamber divided into at least three sections and placed under a reduced pressure under the action of the inertia force of the toner particles supplied together with a gas stream and the centrifugal force of the curved gas stream due to Coanda effect. A first gas introduction pipe and a second gas introduction pipe are disposed above the classifying chamber so as to provide a first inlet and a second inlet opening with the first inlet being disposed closer to the supply nozzle than the second inlet. The absolute values of the static pressures P.sub.1 and P.sub.2 in the first and second gas introduction pipes are controlled so as to satisfy the relations of: .vertline.P.sub.1 .vertline..gtoreq.150 mm.aq., .vertline.P.sub.2 .vertline..gtoreq.40 mm.aq. and .vertline.P.sub.1 .vertline.-.vertline.P.sub.2 .vertline..gtoreq.100 mm.aq.
