  • Patent number: 6506477
    Abstract: Data defining an outline shape of a section, color-region image data and adhesion-region image data are generated, color toners are transferred onto a color region and an adhesion region on a sheet in accordance with the respective image data, the sheet is aligned on processed sheets and laminated thereon. Next, a laminated body of the sheets is bonded by heating and pressurizing, and the laminated and bonded sheets are cut along the sectional outline shape. Further, sectional shape data of a solid model are generated and a transparent toner is transferred as an adhesive onto the adhesion region of the sheet. Then, after aligning and laminating the sheet on the processed sheets, the transparent toner is melted to bond the sheets. Color toners are transferred onto the color region of the sheet and the sheet is cut along the outline shape. Furthermore, the color region is defined on a transparent sheet in accordance with the sectional shape of the solid model.

  • Patent number: 5543905
    Abstract: A fixing device has a hollow fixing roller, and a pressing roller pressingly contacting the fixing roller to cooperate with the fixing roller to form a nip portion therebetween so as to fuse and fix a toner image onto a recording paper. The fixing device also has a heating element arranged within the fixing roller at a position eccentric from the axis of the fixing roller toward the nip portion, to locally heat the inner wall of the fixing roller at a position corresponding to the nip portion, so as to decrease the time necessary to heat the fixing roller, to prevent offset, and to prevent the recording paper from being wound onto the fixing roller.

  • Patent number: 5303016
    Abstract: An image fixing device for an image forming apparatus, comprises a hollow cylindrical fixing roller, and cylindrical pressure roller which is kept in contact with the fixing roller so as to rotate in accordance with rotation of the fixing roller. The pressure roller cooperates with the fixing roller to form therebetween a nip extending in a direction of the longitudinal axes thereof and serving to receive a sheet to which a toner image is transferred. The fixing roller is provided with a heater for locally heating the inner wall of the fixing roller at a location corresponding to the nip to fix the toner image to the sheet.
