PURPOSE: A toner for an electric photography and a method for manufacturing the same are provided to prevent the occurrence of photography contamination problems and secure the superior durability, electrification characteristic, and fusing characteristic. ;CONSTITUTION: A method for manufacturing a toner for an electric photography includes the following: A first binder resin, a second binder resin, a releasing agent, a coloring agent, a charge modifier, and an ionomer are mixed. The second binder resin is derived from biomass. The mixed result is milled and extruded. The extruded result is cooled and solidified, and a pulverizing process and a classifying process are followed. The classified result is coated with an external addition layer containing silica, metal oxides, and polymer beads. The toner is supplied using a toner supplying unit(100) composed of a toner tank(101), a supplying unit(103), a toner transferring unit(105), and a toner stirring unit(110).;COPYRIGHT KIPO 2011
