    摘要: This invention relates to a charge transport dual layer for use in a multilayer photoreceptor comprising a support layer, a charge generating layer and a charge transport dual layer including a first transport layer containing a charge-transporting polymer, and a second transport layer containing a charge-transporting polymer having a lower weight percent of charge transporting segments than the charge-transporting polymer in the first transport layer. This structure has greater resistance to corona effects and provides for a longer service life. The charge-transporting polymers preferably comprise polymeric arylamine compounds.
