    摘要： An electrophotographic photoconductor has an electroconductive support, and a photoconductive layer which is formed thereon and contains an aromatic polycarbonate resin including at least a structural unit of formula (1): wherein a, b, c and d are each independently an integer of 0 to 4; n is an integer of 0 or 1; and R1, R2, R3 and R4 are each independently a halogen atom, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted alkoxyl group having 1 to 6 carbon atoms, or a substituted or unsubstituted aryl group, and R1, R2, R3 and R4 may each be the same or different when a, b, c and d are each an integer of 2, 3 or 4. Further, there are provided aromatic polycarbonate resins each including the structural unit of formula (1) and a structural unit with charge transporting properties.

    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.
