Prolonged exposure of a commercial organic photoconductor in a plasma environment corresponding to an industrial electrophotographic process caused the formation of a parasitic surface layer with properties that are different from the original photoconductor. The parasitic film consists of a heavily oxidized surface region and oxygen-free subsurface layer with a chemical composition similar to the original photoconductor but having a significantly different bonding arrangement. The formation of this film has been correlated with damage induced by the energetic particles and UV photons originating from the electrophotographic plasma discharge. An in-depth understanding of the formation and the properties of this parasitic layer could provide an effective means to overcome its detrimental impact on printing cost and quality.
