Process for preparing polymerized toner
The present invention relates to a process for preparing a polymerized toner, and in particular to a process for preparing a polymerized toner and a polymerized toner prepared therefrom, wherein a certain block copolymer and copper phthalocyanine are used within a predetermined range of the amounts for a carbon black dispersant during a suspension polymerization, thereby making it possible to realize a narrow particle sizes distribution, high transcription efficiency, and an enhanced image concentration.
