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.

An improved toner comprises a binder resin comprising a urea-modified polyester resin; a colorant master batch comprising a colorant; a resin; and a pigment dispersant. The toner is prepared by a method comprising dissolving or dispersing toner compositions including a modified polyester resin capable of forming the urea-modified polyester resin and the colorant master batch in an organic solvent to provide a liquid; dispersing the liquid in an aqueous medium including resin fine particles while reacting the modified polyester resin with at least one of a crosslinker and an elongation agent to provide particles; and washing the particles after removing the organic solvent therefrom.

摘要:
A color toner which gives a suitable image gloss and has an excellent color reproducibility, which has sufficient anti-offset properties even when a release oil is not coated on a fixing roller or is coated in only a small amount, and which has excellent transfer properties, durability, and charge stability relative to humidity is disclosed. Also, an image-forming apparatus using the color toner and a toner container filled with the color toner are disclosed. The color toner comprises a continuous phase of a resin containing a urea-modified polyester resin; and a modified resin dispersed in the continuous phase, wherein the modified resin contains a release polymer portion containing a release polymer; and a modified portion containing a plurality of vinyl monomer units, the modified portion having an average ester group concentration of 8% by weight to 30% by weight.
