    摘要： 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.

    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 composition to form an overcoat layer for an organic photoreceptor includes an organic silane compound, an alcohol-soluble polymer, and a solvent. When the composition is used in forming an overcoat layer, it is not necessary to coat a primer or an adhesive layer to improve adhesion, thus simplifying a coating process and reducing the cost required in forming additive layers. Also, since the organic photoreceptor has a high durability, the life characteristics of electrophotographic organic photoreceptor may be increased. Further, in an electrophotographic imaging process, a decrease in charge potential and a rise in the residual potential can be reduced, thus improving the life characteristic of the organic photoreceptor.

    摘要： A double-layered positively-charged organic photoreceptor has a charge transport layer with effective adhesion to an electroconductive support and effective resistance against dissolving when in contact with a hydrocarbon-based solvent of a wet developer. Therefore, the double-layered positively-charged organic photoreceptor requires neither anodizing on the electroconductive support nor an additional adhesive layer, and is compatible with wet developing methods. The double-layered positively-charged organic photoreceptor includes: an electroconductive support; a charge transport layer formed on a surface of the electroconductive support and including a charge transport material for transporting holes, a polycarbonate-based first binder resin, and a second binder resin of a polyester copolymer with a biphenylfluorene group; and a charge generating layer formed on the surface of the charge transport layer.
