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. After entirely covering the color region with a white toner layer, a three-primary-color toner layer in which the three primary color toners are spatially tone-distributed is applied to the color region, to form a colored layer…
