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.
