Abstract:
1. A photoconductor consisting of an optional supporting substrate, a photogenerating layer, and a charge transport layer consisting of at least one charge transport component, and wherein said photogenerating layer consists of a mixture of a hydroxygallium phthalocyanine, a hydroxyaluminum phthalocyanine, a polymer binder, and a silanol, said silanol being selected from the group consisting of trisilanolisooctyl POSS, trisilanolphenyl POSS, trisilanolisobutyl POSS, trisilanolcyclohexyl and trisilanolcyclopentyl POSS, wherein POSS is a polyhedral oligonmeric silsesquioxane, said hydroxygallium phthalocyanine being present in an amount of from about 30 to about 80 weight percent, said hydroxyaluminum phthalocyanine being present in an amount of from about 0.001 to about 0.1 weight percent, said silanol being present in an amount of from about 0.1 to about 20 weight percent, and said polymer binder being present in an amount of from about 20 to about 70 weight percent of the photogenerating layer components, and wherein the total of said components is about 100 percent and wherein said silanol is free of chemical bonding to said hydroxygallium phthalocyanine, and said silanol is free of chemical bonding to said hydroxyaluinum phthalocyanine.
