Abstract
A liquid developer for high-quality image reproduction and a method of preparing the liquid developer. The liquid developer exhibits good pigment dispersion by the introduction of organosol. The liquid developer contains fine toner particles of a uniform size with a volume-average to number-average particle diameter ratio of 1.5-2.5, and thus can produce high-resolution images. The liquid developer preparation method is environmentally friendly, simple, and cost effective because no cosolvent is used, thus eliminating the need for a cosolvent removal process.
