Abstract
The present invention is directed to an electrophotographic photoreceptor which is smooth without orange peel, inhibits the rise of a residual potential and the drop of a charged potential, and is excellent in stability even when it is repeatedly used. The photoreceptor comprises a charge generation material, a charge transport material, a polyarylate having a polymerization degree of 10 to 5,000, a polycarbonate having a polymerization degree of 10 to 5,000, and a polydimethylsiloxane having a polymerization degree of 0 to 2,000.
