Removing Fixed Image From Receiver Patents (Class 430/124.15)
  • Patent number: 8497058
    Abstract: An image forming method comprising the step of: forming a toner image employing toner particles containing at least a resin on an image supporting substrate having thereon a toner holding layer via a toner image holding process to form an image print, the toner image being held in the toner holding layer in the toner image holding process, wherein at least the toner particles or the image supporting substrate is separated from the image print via a separation process; and at least the separated toner particles or the separated image supporting substrate is recyclable as an image forming material.

  • Publication number: 20130130172
    Abstract: A method of deinking an image-bearing member using an organic solvent includes receiving the image-bearing member. The member has thereon a continuous or discontinuous image layer formed of toner particles that do not include colorant, and colorant particles or molecules. The colorant particles or molecules are arranged in a pattern corresponding to the arrangement of the toner particles. The organic solvent is hydrophobic or oliophilic and the colorant is insoluble in the organic solvent. The hydrophobic or oliophilic organic solvent is applied to the image-bearing member, so that a majority of the toner image layer is dissolved off the image-bearing member and the colorant is removed from the image-bearing member. A deinked reflection density of the image-bearing member in a selected test area from which the toner image layer was dissolved is within 0.15 of an imprinted reflection density of the image-bearing member before deinking.

  • Patent number: 8431293
    Abstract: A method of recycling an image forming material comprising the steps of holding a toner image formed by employing toner particles in a toner holding layer formed on an image supporting substrate to form a first generation image print, separating the toner particles from the first generation image print; and recycling the separated toner particles to form a second generation image print by holding a toner image formed by employing the separated toner particles in a toner holding layer formed on an image supporting substrate, provided that the image forming material comprises at least toner particles, wherein Condition (1) 0.9?B/A?0.1 and Condition (2) 1?C/A?0.9 are satisfied, A, B and C representing particle shape factors of original toner particles, toner particles held in the image holding layer of the first generation image print; and separated toner particles, respectively.

  • Publication number: 20090023090
    Abstract: The present invention provides a support for image recording material etc. that can record high-quality images far from occurrences of blister, uneven recording or uneven fixing. In order to attain the object, a support for image recording material is provided that comprises a raw paper, and at least one polyolefin resin layer on both sides of the raw paper, wherein two or more polyolefin resin layers are disposed at the front side where an image recording layer is to be disposed, polypropylene resin is included within at least one polyolefin resin layer at the front side other than the outermost polyolefin resin layer at the front side, and the content A (% by mass) of polypropylene resin within the at least one polyolefin resin layer at the front side other than the outermost polyolefin resin layer is higher than the content B (% by mass) of polypropylene resin within the outermost polyolefin resin layer at the front side.
