  • Patent number: 6156127
    Abstract: In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a transfer paper sheet, the toner on the transfer paper sheet is heated to be melted or softened. An offset belt having adhesive force stronger than that between the transfer paper sheet and the toner comes in contact with the toner. The toner is separated and removed from the transfer paper sheet when the offset belt and the transfer paper sheet are separated from each other. Heating of the toner is maintained until the transfer paper sheet is separated from the offset belt. The transfer paper sheet is separated from the offset belt before the toner is cooled and solidified. A toner heating maintaining device is constructed by using a heating-supporting member having a heater therein and arranged such that the transfer paper sheet and the offset belt are supported between the heating-supporting member and a heating roller.

  • Patent number: 5769957
    Abstract: In a regenerating method and apparatus of a recorded material in which at least a portion of the recorded material in the vicinity of a surface thereof on an image forming side is wet and expands with a liquid, the wet and expanding liquid (also called an image removing accelerating liquid in the following description) is provided to the recorded material so that the portion of the recorded material in the vicinity of the surface thereof is wet and expands with this liquid. A separating member comes in contact with an image forming substance having a film shape and a thermoplastic or thermally melted property and formed in the vicinity of the surface of the recorded material in a state in which joining force between the image forming substance and the recorded material is reduced. An image in the vicinity of the surface of the recorded material is transferred onto the separating member so that the image forming substance on the recorded material is removed therefrom.
