PURPOSE: A method for forming the electrophotographic image is provided, to improve the initial electrostatic characteristic and to prevent the change of electrostatic characteristic after dipped into the solvent for a liquid developer, thereby preventing the erosion of a photoreceptor and the contamination. CONSTITUTION: The method comprises the step of directly contacting an electrophotographic organic photoreceptor with a liquid developer, wherein the binder contained on the surface layer of the organic photoreceptor is comprises a polyester resin having the biphenyl fluorene repeating unit represented by the formula 1, wherein the hydrogen atom on an aromatic ring is unsubstituted or substituted by a group selected from the group consisting of a halogen atom, an aliphatic hydrocarbon group of C1-C20 and a cycloalkyl group of C5-C8. Preferably the polyester resin has a weight average molecular weight of 20,000-200,000 and its content is 50-100 wt% based on the total weight of the binder used on the surface layer of the photoreceptor.
