Forming Overlayer On Developed Image Patents (Class 430/126.1)
  • Patent number: 9037065
    Abstract: In a first thermal transfer portion of upstream side, a negative toner image forming portion forms on a photosensitive drum a desired negative toner image which reverses a desired positive toner image selected from all the toner images. The negative toner image forming portion then forms the desired negative toner image on a belt member. The first thermal transfer portion transfers a desired negative foil image from a foil sheet to the belt member so that a desired positive foil image remains on the foil sheet. A second transfer portion transfers the desired positive foil image thus remained on the desired positive toner image formed on the sheet of paper. A cleaning portion removes the desired negative toner image and the desired negative foil image from the belt member.

  • Patent number: 8735043
    Abstract: Image noise is reduced in halftone imaging processes by placing clear toner particles around the colored toner particles. The clear toner particles must be placed around the colored toner particles prior to transferring the developed image from an imaging member to a receiving member or substrate. The clear toner particles force the colored toner particles to remain in their deposited location during transfer. The result is an image with less mottle and graininess.

  • Patent number: 7666329
    Abstract: The invention provides conductivity control agent comprised of a polymeric material containing hydroxyalkylphosphonium (2-hydoxyethoxycarbonyl) arylsulfonate salts. The conductivity control agents can be used with semi-conductive rolls, belts and other biasable members. The inclusion of the conductivity control agent in the polymeric or polyurethane elastomers extends the electrical life of the polyurethane biasable member in low humidity environments. Additionally, the resistivity of the elastomeric polyurethane or polymer on the biasable member is controlled to a desirable value by adjusting the conductivity control agent level in the polymeric or polyurethane elastomers.
