摘要： An electrophotographic photoconductor has an electroconductive support, and a charge generation layer and a charge transport layer successively formed on the electroconductive support, the charge transport layer allowing any monochromatic light with a wavelength in a wavelength region of 390 to 460 nm to pass through and exhibiting a fluorescence generation coefficiency of 0.8 or less when irradiated with the monochromatic light. An electrophotographic image forming apparatus and a process cartridge employ the above-mentioned photoconductor.

摘要： An electrophotographic photoconductor includes an electroconductive support and a photoconductive layer formed thereon which contains a compound having a charge generating moiety and a charge transporting moiety in the molecule thereof. As such a compound for use in the electrophotographic photoconductor, various compounds having a charge generating moiety derived from an azo compound and a charge transporting moiety derived from a triarylamine compound are proposed. Bisazo and trisazo compounds serving as such compounds are also proposed, together with intermediates for producing the bisazo and trisazo compounds.
