  • Patent number: 8320811
    Abstract: An image recording medium that can be repeatedly used by removing the toner image has a three-layered structure formed of a heat-resistant resin sheet and a pair of releasing and light absorptive layers coated on both sides of the heat-resistant resin sheet. The releasing and light absorptive layer generates heat by absorbing laser so as to fuse and fix the toner image formed on the special sheet surface at the time of image forming, and assures pertinent releasing performance at the time of image removal so as to facilitate removal of the re-fused toner image. Each releasing and light absorptive layer may be split into a light absorptive layer and a releasing layer. The heat-resistant resin sheet may be produced by adding an infrared absorbent to a heat-resistant resin sheet to serve as a heat-resistant sheet and a light absorptive layer.

  • Patent number: 8311471
    Abstract: An image forming apparatus forms a gloss mark with colored toner without using clear toner. This is accomplished by fixing an image composed of only part of the color toner required for forming an image, the rest of the required color toner being denoted as residual toner. Specifically, at an area of at which a decreased gloss is desired, an image is formed using a part of colored toner required for forming the image and fixed on a sheet, and then, applied to the sheet is the residual quantity of toner so as to be superimposed on the fixed colored toner.

  • Patent number: 8190076
    Abstract: A transparent toner image forming device forms a transparent toner image on a sheet on which a color toner image is fixed. Image information that is designated by a user for forming the transparent toner image on part of the sheet is obtained. Application of the transparent toner is controlled such that, when the color toner is fixed in an amount not less than a predetermined first amount per unit area in a first region designated so as not to form the transparent toner image on the basis of image information, the transparent toner image is formed in a predetermined second amount per unit area in the first region. The transparent toner image is formed in an amount not less than the predetermined second amount per unit area in a second region designated so as to form the transparent toner image on the basis of the image information.

    Abstract: The invention describes a method and a device for generating a prespecified gloss pattern on a toner image in order to develop a detection property of said toner image. In the method, toner that is first heated to above its glass transition temperature is brought into contact with a glosser belt, said glosser belt having—corresponding to the gloss pattern to be generated—at least one first area displaying a first surface roughness and at least a second area displaying a second surface roughness and/or displaying a different elevation whereas a plurality of second areas is provided within the first area displaying a specific pattern, which repetition on other glosser belts is not allowed so that an identification of specific glosser belts and thus an identification of a glosser device is easier. Subsequently, while the toner is in contact with the glosser belt, said toner is cooled to below its glass transition temperature.
