ELECTROPHOTOGRAPHIC PHOTORECEPTOR.

摘要

An electrophotographic photoreceptor improved in electrostatic characteristics and image pickup and particularly excellent in the reproduction of highly precise images by the use of a liquid developer and in the image pickup according to the scanning exposure system using low-output laser beams. The photoreceptor contains a binder resin comprising at least one resin (A) containing at least 30 wt % of a polymer component of general formula (I) and 0.5 to 15 wt % of a specified polar polymer component and having a weight average molecular weight of 1x10<3> to 2x10<4> and at least one resin (B) comprising a star polymer having at least three polymer chains bonded together in an organic molecule, each of said chain containing a specified polar polymer component and a polymer component of formula (I), and having a weight average molecular weight of 3x10<4> to 1x10<6>. In formula (I) a<1> and a<2> represent each hydrogen, halogen, cyano, hydrocarbyl, or COOR<4> optionally bonded via hydrocarbyl (wherein R<4> represents hydrocarbyl); and R<3> represents hydrocarbyl.
