摘要： A method including: (a) dispensing an electrically conductive liquid into a contact member permeable to the liquid; (b) rubbing the contact member and a surface against each other, at a contact length greater than a tangential contact length, to release the liquid from the contact member to wet the surface with the electrically conductive liquid in a layer ranging in thickness from about 1 to about 100 micrometers; and (c) electrifying the liquid at any time effective for imparting an electrical charge to the surface.

摘要： A charge transport layer material for a photoreceptor includes at least a polycarbonate polymer binder having a number average molecular weight of not less than 35,000, at least one charge transport material, polytetrafluoroethylene particle aggregates having an average size of less than about 1.5 microns and a fluorine-containing polymeric surfactant dispersed in a solvent mixture of at least tetrahydrofuran and toluene. The dispersion is able to form a uniform and stable material ideal for use in forming a charge transport layer of a photoreceptor. The resultant charge transport layer exhibits excellent wear resistance against contact with an AC bias charging roll, excellent electrical performance, and delivers superior print quality.

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.
