Aromatic polyester resin, and electrophotographic photoconductor and image forming apparatus using thereof

摘要

The object of the invention is to provide a novel aromatic polyester resin useful as a binder resin or charge transporting polymer for an organic photoconductor and an electrophotographic photoconductor having high sensitivity and high durability produced using the above-noted novel aromatic polyester resin. For this object, the invention provides an aromatic polyester resin which has a recurring unit represented by the following Formula (I) and an electrophotographic photoconductor produced using the above-noted aromatic polyester resin. wherein R¹ represents any one of a hydrogen atom, an unsubstituted or substituted alkyl group and an unsubstituted or substituted aryl group; Ar¹ represents an unsubstituted or substituted aryl group; Ar² and Ar³ may be the same as or different from each other and represent respectively an unsubstituted or substituted arylene group; and W represents an unsubstituted or substituted divalent aromatic group.
