Abstract

An electrophotographic imaging member including PA0 at least one photographic imaging layer and PA0 a partially electrically conductive overcoat layer including PA1 finely divided charge injection enabling particles dispersed in PA1 a charge transporting continuous matrix including a cross linked polyamide, charge transport molecules and oxidized charge transport molecules, the continuous matrix being formed from a solution selected from the group including PA2 a first solution including PA3 crosslinkable alcohol soluble polyamide containing methoxy methyl groups attached to amide nitrogen atoms, PA3 an acid having a pK.sub.a of less than about 3, PA3 a cross linking agent selected from the group comprising a formaldehyde generating cross linking agent, an alkoxylated cross linking agent, a methylolamine cross linking agent and mixtures thereof, PA3 a dihydroxy arylamine, and PA3 a liquid selected from the group including alcohol solvents, diluent and mixtures thereof, PA2 a second solution including PA3 crosslinkable alcohol soluble polyamide free of methoxy methyl groups attached to amide nitrogen atoms, PA3 an acid having a pK.sub.a of less than about 3, PA3 an alkoxylated cross…
