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): ##STR1## wherein R.sup.1 and R.sup.2 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 ##STR2## 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.
