Abstract
A photoconductive imaging member including a hole blocking layer, a photogenerating layer, and a charge transport layer, and wherein the hole blocking layer contains, for example, a metal oxide; and a mixture of a phenolic compound and a phenolic resin, and wherein the phenolic compound can contain at least two phenolic groups.
Claims16
An imaging member comprised of a supporting substrate, a hole blocking layer thereover, a photogenerating layer, and a charge transport layer, and wherein the hole blocking layer is comprised of a metal oxide, and a mixture of two phenolic resins of a first phenolic resin and a second phenolic resin with dissimilar weight average molecular weights, and wherein said first phenolic resin possesses a lower weight average molecular weight than said second phenolic resin, and wherein said second phenolic resin's weight is from about 1,000 to about 10,000 lower than said first phenolic resin.
A photoconductive imaging member comprised of a supporting substrate, a hole blocking layer, a photogenerating layer, and a charge transport layer, and wherein the hole blocking layer is comprised of a metal oxide, at least two phenolic resins and a phenolic compound, and wherein said metal oxide is chromium oxide.
A photoconductive imaging member comprised of a supporting substrate, a hole blocking layer thereover, a photogenerating layer, and a charge transport layer, and wherein the hole blocking layer is comprised of a metal oxide, and a mixture of at least two phenolic resins with dissimilar weight average molecular weights and wherein at least two is two, and wherein said mixture is comprised of a first phenolic resin with a weight average molecular weight of from about 3,000 to about 17,000, and a second phenolic resin with a weight average molecular weight of from about 700 to about 1,500.
