Patent number: 6839524Abstract: An image forming apparatus can form an image of a high-precision security information for anti-reproduction. A photosensitive material-coated area in a recording paper is exposed with an exposure unit to form an image of a high-precision security information. Since the image of the security information is thus formed by exposing the photosensitive material, it can be formed as an image incapable of reproduction.Type: GrantFiled: September 17, 2002Date of Patent: January 4, 2005Assignee: Fuji Xerox Co., Ltd.Inventors: Shoji Yamaguchi, Mario Fuse, Hideki Fukunaga, Tetsuya Kimura

Patent number: 6801723Abstract: A method and apparatus for an image-forming device having at least one patterned roller for affecting the amount of toner present on a print medium when the print medium is advanced through a paper path of the image-forming device and contacts the at least one patterned roller. The roller includes a purposeful pattern that is formed in an outer surface of the roller. The purposeful pattern is configured to form an identifying mark on a print medium as a result of the amount of toner present on the print medium.Type: GrantFiled: December 2, 2002Date of Patent: October 5, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: William I. Herrmann, Bradley J. Anderson, Bruce L. Johnson, Leonard T. Schroath

Publication number: 20040175191Abstract: An image forming apparatus has a first image forming unit and a second image forming unit that form images by different methods on the same page. The image formed by the second image forming unit is used as an identifying image to distinguish an original document made by the image forming apparatus from copies of the original document. The second image forming unit may, for example, emboss or punch holes in the printing medium. The second image forming unit may accordingly be a serial impact dot matrix printing unit or a stamping unit, while the first printing unit may be, for example, an ink jet printing unit or an electrophotographic printing unit. One of the two image forming units is preferably capable of making copies by printing on multiple-ply forms.Type: ApplicationFiled: March 2, 2004Publication date: September 9, 2004Inventor: Hidehito Jingu

Patent number: 6678493Abstract: The specification discloses an image forming apparatus which forms a visual image on a belt transfer member by at least one of image forming units and transfers the formed visual image onto a recording medium with the aid of the belt transfer member. In the image forming apparatus, the belt transfer member includes an endless belt wound on a plurality of tension rolls. A bending member, which bends the endless belt toward the inside of a tangential line connecting points on the outer circumferences of a couple of tension rolls, and locates the bent endless belt inside the tangential line, is additionally provided outside the endless belt located between at least the couple of adjacent tension rolls. An image forming unit may be additionally provided within an outside bending concave region of the endless belt, which is bent by the bending member and the tension rolls adjacent to the bending member.Type: GrantFiled: March 15, 2002Date of Patent: January 13, 2004Assignee: Fuji Xerox Co., Ltd.Inventors: Ryuichiro Maeyama, Yoshikazu Okamoto
