    Abstract: An image forming apparatus having a developer controlling apparatus for a developing roller is provided to uniformly control an amount of developer deposited on the developing roller and a developer controlling method thereof. The apparatus includes a sensing part having a first sensor which senses a conductivity of a liquid developer and a second sensor which senses a density of the liquid developer. A control part controls a voltage applied to the developing roller and/or a deposit roller according to the conductivity and the density sensed by the sensing part.

    Abstract: A multi-layered electrophotographic positively charged organic photoconductor includes a conductive substrate, a charge transport layer formed on the conductive substrate, and a charge generating layer formed on the charge transport layer. A composition to form the charge transport layer includes at least one hole transport material, a binder resin and an organic solvent, and a composition to form the charge generating layer includes a charge generating material, a binder resin, an organic solvent and a hole transport material. An organic photoconductor has improved static electrical properties by controlling interfacial conditions of the charge transport layer and the charge generating layer. The charge generating layer may be readily coated on the charge transport layer. In addition, the organic photoconductor has excellent electric properties such as an improved sensitivity and a low discharge voltage.

    Abstract: A liquid toner composition and a preparation method utilize a colorant, an organosol, a charge control agent, a carrier liquid, a dispersion assistant agent, and a photoreactive catalyst, in which the dispersion assistant agent is a polymer including an unsaturated functional group to cause photopolymerization in a presence of the photoreactive catalyst, and the photoreactive catalyst produces a free radical through an irradiation of light, and initiates the photopolymerization of the dispersion assistant agent. According to embodiments of the present invention, the toner organosol rarely affects the physical properties required of the liquid toner, and an offset error in a fixing operation is removed, resulting in an improved quality of a printed image.
