  • Patent number: 5352558
    Abstract: A device for increasing the solids content of an image formed from liquid developer comprising a belt which is comprised of an absorption material containing small pores to absorb dispersant from a dispersant laden image and a pair of rollers bearing the belt wherein the belt on one of the rollers contacts a dispersant laden image bearing portion of an image carrying member such as a photoreceptor drum or an intermediate sheet.

  • Patent number: 5332642
    Abstract: In a device and method for increasing the solids content of an image formed from a liquid developer, absorption material is contacted with a toner dispersant laden image, and the absorbed dispersant is vacuumed out of the absorption material. The absorption material preferably is a conductive cover on a porous roller biased with an electrical charge which is the same as the charge of the toner particles, such that the resulting electric field repels the toner particles from the absorption material so that minimal toner particles are transferred to the absorption material.

  • Patent number: 5233396
    Abstract: A toner image is transferred from an electrostatographic imaging member to an image receiving substrate. A biased transfer member in the form of a roller or a belt forms a nip with the imaging member. A compliant intermediate transport member passes through the nip for receiving a toner image from the imaging member. The intermediate transport member is preferably semiconductive, and self-discharges in less than one second. In a preferred process for transferring the toner image to a conductive conformable intermediate, both the intermediate transport member and the biased transfer roller are conductive.
