Mechanical properties of toner can be obtained at room temperature by controlling rheological properties of toner. The developing properties and fixing properties of toner for electrophotography can be improved by lowering viscosity at a high temperature, and thus image quality can be stabilized.

摘要： 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.

摘要： A composition for an overcoat layer suitable for use in an organophotoreceptor for liquid toner, an organophotoreceptor manufactured by employing the composition and an electrophotographic imaging apparatus containing the organophotoreceptor. Since the organophotoreceptor can maintain higher charge potential and low residual or discharge potential, the lifetime of the organophotoreceptor can be extended. Also, since the organophotoreceptor has good solvent resistance and abrasion resistance, it can be advantageously used for liquid toner.
