    摘要: A method of producing an aromatic polycarbonate resin includes the step of carrying out solution polymerization of a diphenol compound having a triarylamine structure with a diol compound of formula (I): wherein R1 and R2 are each independently a substituted or unsubstituted alkyl croup, a substituted or unsubstituted aryl group, or a halogen atom; a and b are each independently an integer of 0 to 4: and Y is —COO— or in which Z is a substituted or unsubstituted bivalent aliphatic group or a substituted or unsubstituted arylene group. In addition, an electrophotographic photoconductor has an electroconductive support, and a photoconductive layer formed thereon containing as an effective component the above-mentioned aromatic polycarbonate resin prepared by the solution polymerization.
