  • Patent number: 5148222
    Abstract: Liquid toner imaging apparatus including an image bearing surface, apparatus for developing an image on the image bearing surface using a liquid toner including carrier liquid and pigmented particles, and apparatus for transferring a developed image from the image bearing surface to a substrate. The apparatus for developing includes a developer electrode having a developer surface portions of which sequentially come into propinquity with the image bearing surface and subsequently leave propinquity therewith, each region forming a development region during its propinquity and a stationary nozzle for providing liquid toner of a given color to the development region by supplying liquid toner onto a portion of the developer electrode, wherein the nozzle is spaced more than 8.4 mm from any other nozzle which supplies liquid toner of the given color to the development region.

  • Patent number: 5047808
    Abstract: An image system including an image bearing surface and an intermediate transfer member operative for transfer of liquid toner images from the image bearing surface to a substrate provides for first transfer engagement between the intermediate transfer member and the image bearing surface for transfer of an image from the image bearing surface to the intermediate transfer member at a first pressure, producing deformation of the intermediate transfer member to a first deformation degree. The system provides for second transfer engagement between the intermediate transfer member and the substrate for transfer of the image from the intermediate transfer member to the substrate at a second pressure, producing deformation of the intermediate transfer member to a second deformation degree.
