Abstract:
An electrophotographic photoconductor, comprising:an electroconductive support, and a photoconductive layer formed thereon comprising as an effective component an aromatic polycarbonate resin consisting essentially of a structural unit of formula (2) and a structural unit with charge transporting properties, wherein an amount of said structural unit of formula (2) is 58 to 60 mole percent and an amount of said charge transporting unit is 40 to 42 mole percent based on said polycarbonate resin: wherein a and b are each independently an integer of 1 to 4; and R3 and R4 are each independently a halogen atom, an alkyl group having 1 to 6 carbon atoms, which may have a substituent, an alkoxyl group having 1 to 6 carbon atoms, which may have a substituent, or an aryl group which may have a substituent, and R3 and R4 may each be the same or different when a and b are each an integer of 2, 3 or 4;wherein said structural unit with charge transporting properties is represented by formula (1â€²): wherein R11 is a hydrogen atom, an alkyl group which may have a substituent, or an aryl group which may have a substituent; Ar1 and Ar2 are each an arylene group which may have a substituent; and R12 is an aryl group which may have a substituent.
