ABSTRACT:
Methods of using improved liquid toner dispersions in high-speed electrophotography are disclosed wherein pigment charge homogeneity and mobility are improved by the addition of effective carrier liquid-insoluble monomeric organic acids to the toner solution. Preferred acids include benzoic, succinic, p-toluenesulfonic acid, phenylphosphonic acid, salicylic acid, and 2-nitro and 4-nitrobenzoic acid.
