Abstract:
1. A photoconductor consisting of a supporting substrate, a photogenerating layer, and at least one charge transport layer comprised of at least one charge transport compound, wherein said at least one charge transport layer is comprised of a top charge transport layer and a bottom charge transport layer, and wherein said top charge transport layer is in contact with said bottom charge transport layer and said bottom charge transport layer is in contact with said photogenerating layer, each of said bottom and said top charge transport layer containing from about 50 to about 75 weight percent of said charge transport compound, and wherein said charge transport compound comprises aryl amine molecules as represented by at least one of the following formulas/structures, wherein X is selected from the group consisting of at least one of alkyl, alkoxy, aryl, and halogen, and wherein each of said bottom and said top charge transport layer includes an optional antioxidant comprised of at least one of a hindered phenolic and a hindered amine wherein X, Y and Z are independently selected from the group consisting of at least one of alkyl, alkoxy, aryl, and halogen, and wherein said photogenerating layer contains a thiuram tetrasulfide additive of the following formulas/structures present in an amount of from about 0.1 to about 10 percent by weight, and which thiuram tetrasulfide additive excludes dipentamethylenethiuramtetrasulfide wherein each R is independently selected from the group consisting of at least one of hydrogen, alkoxy, and aryl, and x represents 4.
