摘要： An aromatic block polycarbonate resin is prepared by polymerizing a diphenol compound of formula (2) or (4), a diol compound of formula (1) or (5), and a halogenated carbonyl compound. The diphenol compound of formula (4) is produced by polymerizing the diphenol compound of formula (2) and a halogenated carbonyl compound by solution or interfacial polymerization. An electrophotographic photoconductor has an electroconductive support and a photoconductive layer formed thereon containing the above-mentioned aromatic block polycarbonate resin. An electrophotographic image forming method or apparatus employs the above-mentioned photoconductor. A process cartridge holds therein the photoconductor and at least one of the electrophotographic image forming units.
