Abstract
An electrophotographic photoconductor includes a conductive substrate having a photoconductive film thereon. The photoconductive film includes a layer containing a charge transport agent and a phosphonite compound, which acts as an antioxidant. Preferably, the phosphonite compound is diarylarylphosphonite. The layer that contains the charge transport preferably contains from 0.005 to 10 weight % of diarylarylphosphonite. The diarylarylphosphonite is preferably a compound selected from the group consisting of bis(2,4-di-tert-butylphenyl)phenylphosphonite, bis(2,6-di-tert-butylphenyl)phenylphosphonite and bis(2,6-di-tert-butyl-4-methylphenyl)phenylphosphonite.
