  • Patent number: 5457523
    Abstract: A device for applying an electrical charge to a charge retentive surface by transporting ions in a fluid media and transferring the ions to the member to be charged across the fluid media/charge retentive surface interface. The fluid media is positioned in contact with a charge retentive surface for depositing ions onto the charge retentive surface. In one specific embodiment, the fluid media is a ferrofluid material wherein a magnet is utilized to control the position of the fluid media, which, in turn, can be utilized to selectively control the activation of the charging process.

  • Patent number: 5258461
    Abstract: Polymer films are formed by electrocodeposition of solutions containing a dispersion of charged particles of a first polymer and charged particles of a second polymer. Microheterogeneous films are obtained having micro-domains of a minor component polymer dispersed in the major component polymer. Processes for preparing dispersions for electrocodeposition are also provided In a first process, two polymers are dissolved in a common solvent and then dispersed as small charged particles in another solvent which is a precipitant for both polymers. In another process, a dispersion of a first polymer is prepared by adding a solution of the first polymer to a dispersant solvent, and then a solution of a second polymer is dispersed in the dispersion of the first polymer. In another process, a solution of the second polymer is added to a dispersion of the first polymer which contains only a single non-solvent for the second polymer.

  • Patent number: 5079121
    Abstract: Disclosed is a seamless belt comprising a laminate of a conducting polymer layer and a host polymer layer. The process for preparing the seamless belt comprises electrochemically polymerizing onto an electrode a layer of a conductive polymeric material, followed by electrophoretically depositing a layer of a host polymer onto the layer of conductive polymeric material. Also disclosed is an imaging member comprising a substrate and a photogenerating layer, wherein the substrate comprises a laminate as described above. An imaging process which comprises incorporating into an ionographic imaging device an imaging member comprising a laminate of a conducting polymer layer and a host polymer layer as described above, generating a latent image on the imaging member by ion deposition, developing the latent image with a toner, transferring the developed image to a substrate, and permanently affixing the transferred image to the substrate is also disclosed.
