Abstract
An electrophotographic photoconductor has an electroconductive support, and a photoconductive layer formed thereon containing as an effective component an aromatic polycarbonate resin having a structural unit of formula (2) and a structural unit with charge transporting properties, each of the structural units being contained in an amount of 5 wt. % or more of the total weight of the polycarbonate resin. There is disclosed an aromatic polycarbonate resin having a structural unit of formula (1) and the structural unit of formula (2), with the relationship between the composition ratios being 0<k/(k+j)<1 when the composition ratio of the structural unit (1) is k and that of the structural unit (2) is j, or an aromatic polycarbonate resin having a repeat unit of formula (3). The formulas (1) to (3) are specified in the specification.
