PURPOSE:To improve the sensitivity and the durability, by using a specific pyrazoline compund as an electric charge transferring substance to a photoreceptor having an electric charge generating layer and an electric charge transferring layer. CONSTITUTION:A pyrazoline compound expressed by general formula[I. [where, X1 is a heterocyclic group which may be substituted (2-pyridyl, 3- pyridyl, 2-quinolyl, 4-quinolyl, 3-carbazolyl etc.) R1 is an alkoxyphenyl group, aryloxyphenyl group. R2 is an aryl group which may be substituted. (n) is 0 or 2.]and a bonding agent are dissolved in a solvent. The solution is aapplied to form an electric charge transferring layer. The layer is regulated to 2-100mu thickness by mixing 10-500weight electric charge transferring compound fasing on 100pts.wt. bonding agent. An electric generating layer is formed on this layer to obtain an electrophotographic receptor. |
