Abstract
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): ##STR1## wherein a, b, c and d are each independently an integer of 0 to 4; n is an integer of 0 or 1; and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 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 R.sup.1, R.sup.2, R.sup.3 and R.sup.4 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.
