    摘要： A test apparatus to evaluate the electrical properties of a liquid toner in which a printing quality of the liquid toner may be predicted by evaluating the electrical properties of the liquid toner without performing printing. The test apparatus to evaluate the electrical properties of a liquid toner includes a roller, a conductive flat panel positioned below the roller to move a predetermined distance in contact with the roller, a power supply device applying a voltage to the roller and the conductive flat panel, and a voltage tester provided at the rear of the roller to move together with the roller, testing a voltage of the liquid toner arranged on the conductive flat panel.

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 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.
