An electrophotographic liquid developer composed of a carrier liquid with a volume resistivity of over 109 OMEGA cm and specific dielectric constant of below 3.5, colored material in fine powder form, a charge control agent selected from the group consisting of a vinyl chloride polymer and nitrocellulose which is insoluble in said carrier liquid, a material selected from the group consisting of resin, oil and mixtures thereof, having high compatability with said charge control agent and being soluble in said carrier liquid, a liquid which dissolves said charge control agent and is compatible with said carrier liquid, and a dispersion stabilizer accounting for less than 20 percent (by weight) and more than 0.5 percent (by weight) of the whole.
