Abstract: An image transferring method for transferring a developer agent layer having a visible image from a developing medium comprising a substrate and the developer agent layer on the substrate to a heat sealing sheet comprising a sheet substrate and a thermoplastic resin layer on the sheet substrate, is disclosed. The method comprises the steps of superposing the developing medium over the heat sealing sheet while the developer agent layer is contacted with the thermoplastic resin layer, supplying the superposed developing medium and the heat sealing sheet with heat and pressure to attach the developer agent layer to the heat sealing sheet through the thermoplastic resin layer, and exfoliating the substrate from the developing medium attached to the heat sealing sheet while fixing the sheet substrate of the heat sealing sheet to a flat or curved surface.

Abstract: An image transferring sheet is made of a combination of a thermally bonding sheet and a developer sheet and a method for fabricating such a sheet is provided. In the image transferring sheet, both sheets are hot-pressed in such a state that a thermoplastic resin layer of the thermally bonding sheet and a developer layer of the developer sheet on which an image has been formed are superposed, and the developer sheet should have a size larger than the thermally bonding sheet. The use of the image transferring sheet ensures easy separation of one sheet from another and transfer of the developer layer of the developer sheet onto the thermally bonding sheet.

Abstract: In a pressure developing device employed in an imaging device like a duplicating machine, an optical printer etc., pressure force for evenly pressurizing a recording medium is capable of being varied in accordance with the width of the recording medium to be pressurized.

Abstract: A developer sheet is composed, in one embodiment, of a reflecting layer formed by securely bonding an aluminum or other metal foil on a substrate and a developer layer formed on the reflecting layer.

Abstract: An apparatus and a method for forming a three-dimensional article with photosetting or thermosetting material on the basis of a three-dimensional information on the article by means of an ink jet method. The material is jetted from at least one ink jet head to a stage and laminated thereon. The laminated material is exposed to light by a light source to be cured. In this process, a jetting direction of the material from the ink jet head to the stage and/or a jetting amount of the material jetted from the ink jet head is changed in accordance with the information by a control unit, thereby forming a solid article having a desired three-dimensional shape.

Abstract: A photocopying system without using an intermediate film is disclosed. In this system, the photo-pressure sensitive sheet and an original are tightly overlapped on a photocopying stage. Scratching scars generated by friction therebetween can be avoided by drive means for changing a distance therebetween. Images on the reverse side of the original can be protected from being duplicated by changing a direction of a light beam. Figure/character images, as well as image trimming, can be arbitrarily photocopied by exposing to a light through display on liquid crystal panel.
