Toner for electrophotography, method of manufacturing the toner, developer, development method, transfer method, and process cartridge using the toner

摘要

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.
