摘要： A method for producing a resin particle dispersion includes: preparing a phase-inverted emulsion by phase inversion emulsification of a resin using an organic solvent and an aqueous medium; and removing the organic solvent from the phase-inverted emulsion by reduced pressure distillation. The reduced pressure distillation is performed using a reduced pressure distillation device including: a distillation tank that contains the phase-inverted emulsion; a heating unit that heats a tank wall of the distillation tank by causing a heated fluid to flow inside the heating unit; and an agitating unit disposed inside the distillation tank, the agitating unit including an agitating shaft and one or plural gutter-shaped agitation impellers that are attached to the agitating shaft, rotate to agitate the phase-inverted emulsion, and draw up the phase-inverted emulsion to form a liquid film of the phase-inverted emulsion on a heat transfer surface of the distillation tank in a portion above a liquid level of the phase-inverted emulsion. The aqueous medium is added to the phase-inverted emulsion contained in the distillation tank during the reduced pressure distillation.

摘要： Provided is a toner blend composition comprising a first pigmented toner and a second toner that is devoid of any pigment additive, i.e., a ‘non-pigmented or clear toner’. The non-pigmented or clear toner is about 1% to about 15% by weight of the toner blend composition. The resulting inventive toner blend composition surprisingly exhibits similar print density on a page compared to a fully pigmented toner. Moreover, this toner blend composition exhibits improvement in toner usage per page, thus lowering toner cost compared to a fully pigmented toner. The non-pigmented or clear toner may be used in combination with either a monochrome or conventional toner using a carbon black pigment, or a chemically processed toners (′CPT″) toners using a black pigment, magenta pigment, yellow pigment or a cyan pigment.
