摘要： A liquid ink composition and a method for producing the same, wherein the liquid ink composition includes a colorant, a charge control agent to regulate electrostatic properties of the colorant, and an organosol to disperse and bind the colorant and the charge control agent. The colorant may be coated with a thermoplastic resin to improve binding with the organosol. By coating the colorant with the thermoplastic resin, the affinity of the colorant for the organosol is facilitated, increasing a size of particles in the liquid ink composition, so that the control of the particles improves the image quality, and micro particles of the carbon black pigment alone do not substantially exist in the printer to prevent printing on a non-image area, thus producing a clear printed image and preventing contamination of other parts in the printer during printing.

摘要： A liquid developer electrophotographic apparatus and method for developing one or more successive color images on a previous color image formed on a latent image retaining body, wherein peeling off the prior color image is prevented by establishing a reversible electrophoretic transfer efficiency of toner particles in the prior toner image to be not greater than 60% in the liquid developer for the successive color image while applying an electrical potential difference between the latent image retaining body and a developing electrode for the successive developing step(s). A resin content of the toner particles forming the previous color image may be selected to achieve the reversible electrophoretic transfer efficiency of 60% or less. Alternatively, or in conjunction with the selected resin content, a heater disposed adjacent to a developing station of the successive color image may be arranged to heat the already developed image or the surface of the latent image retaining body so that the toner particles of the prior developed image has the reversible electrophoretic transfer efficiency of 60% or less.
