Abstract

A process for producing polymerized toner comprises polymerizing a composition containing a polymerizable monomer and a colorant in a medium to form colored resin particles, separating the particles from the medium by filtration, and drying the separated particles. The separation of the particles from the medium is effected by a decanter-type centrifugal separator equipped with an outer rotary cylinder which contains a screw conveyor freely rotating relative to the cylinder.
