ABSTRACT:
A process for producing a polymer toner comprises the steps of pouring a polymerizable monomer composition containing at least a polymerizable monomer and a colorant, but containing no oil-soluble polymerization initiator into an aqueous dispersion medium containing a dispersing agent; adding an oil-soluble polymerization initiator to the polymerizable monomer composition while stirring the composition to form primary droplets thereof, thereby bringing the droplets of the polymerizable monomer composition into contact with droplets of the oil-soluble polymerization initiator to form droplets of a polymerizable monomer composition containing the oil-soluble polymerization initiator; further continuing the stirring to form secondary droplets having desired droplet sizes; and then conducting suspension polymerization of the polymerizable monomer composition.
