Abstract
An electrophotographic liquid toner composition having lower saturation density and method of reducing the saturation density comprising a toner particle formed from a resin, a solid pigment, and a transparent filler, said pigment and said transparent filler having similar surface energies such that they impart similar triboelectric charging properties to said composition, and said composition is further characterized in that the triboelectric properties of said composition are substantially equivalent to the triboelectric properties of a reference composition in which said filler is not present and in which the combined amount of said pigment is equal to the amount of pigment in said reference composition, and in that said transparent filler lowers the saturation density of said composition so that the saturation density of said composition is lower than the saturation density of said reference composition.
