摘要： A photoreceptor and method eliminate interference-fringe print defect due to interference effects caused by reflected beams from various interfaces in a multilayered photoreceptor. The substrate surface is formed with specific dimensions so as to enable the coating of the substrate with an undercoat film including, for example, an organometallic compound or an organometallic chelate compound such as any suitable hydrolyzable organozirconium, organotitanium or organoaluminum compound with a silane. Elimination of the "pepper spot" print defect is accomplished without the addition of a thickening agent to the undercoat film.

摘要： A charge transport layer material for a photoreceptor includes at least a polycarbonate polymer, at least one charge transport material, polytetrafluoroethylene particle aggregates having an average size of less than about 1.5 microns, hydrophobic silica and a fluorine-containing polymeric surfactant dispersed in a solvent. The presence of the hydrophobic silica enables the dispersion to have superior stability by preventing settling of the PTFE particles. A resulting charge transport layer produced from the dispersion exhibits excellent wear resistance against contact with an AC bias charging roll, excellent electrical performance, and delivers superior print quality.
