ABSTRACT:
The method of manufacturing toner for electrophotography includes the steps of dissolving or dispersing a toner composition containing a resin and a coloring agent into polymerizable monomers to provide a solution or a dispersed system, emulsifying the solution or the dispersed system with a first surface active agent in an aqueous medium to provide an emulsion, and polymerizing the polymerizable monomers in the emulsion to obtain toner. A second surface active agent having polarity opposite to polarity of the first surface active agent is added after the emulsifying step.
