| 399339000 | By pressure (without heat) | 7 |
| 20090067904 | FIXER, FIXING DEVICE, AND IMAGE FORMING APPARATUS - A disclosed fixing device fixes resin particles onto a medium by applying a fixer including a softening agent onto the resin particles resting on the medium. The softening agent softens the resin particles by dissolving or causing swelling of at least part of resin included in the resin particles. A foamed fixer is generated from the fixer. The foamed fixer whose layer thickness is controlled is applied onto the resin particles resting on the medium. | 03-12-2009 |
| 20120163889 | Fixing Device - A fixing device includes a tubular member, a nip member, a backup member, and a bias member. The tubular member has an outer peripheral surface, an inner peripheral surface defining an internal space, and an axis defining an axis direction. The nip member is in contact with the inner peripheral surface. The backup member is opposed to the nip member and in contact with the outer peripheral surface to form a nip region for nipping a sheet conveyed in a conveying direction orthogonal to the axis direction. The backup member is configured to move in the conveying direction and the tubular member is configured to circularly move around the axis in accordance with the movement of the backup member due to a friction force generated between the tubular member and the backup member. The bias member protrudes toward the backup member through a bias region. | 06-28-2012 |
| 20120195657 | PRESSURE ROLLER AND FIXING DEVICE EQUIPPED WITH THE SAME - A pressure roller for use in a fixing device includes a core metal, an elastic layer, and a releasing layer. The releasing layer is made of at least one fluorine resin selected from among tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, ethylene-tetrafluoroethylene copolymer, and tetrafluoroethylene-hexafluoropropylene copolymer. The fluorine resin contains at least one polymer selected from among polyvinylidene fluoride, polyacrylonitrile, and polymethyl methacrylate, and monomer electrolyte. | 08-02-2012 |
| 20120195658 | PRESSURE ROLLER AND FIXING DEVICE EQUIPPED WITH THE SAME - A pressure roller for use in a fixing device includes a core metal, an elastic layer, a releasing layer, and an adhesive layer configured to cause the elastic layer and the releasing layer to adhere to each other, wherein the adhesive layer contains monomer electrolyte. | 08-02-2012 |
| 20120301196 | IMAGE PINNING FOR SUBSTRATE MEDIA HANDLING - An apparatus for and method of handling substrate media in a marking device using toner. The apparatus including first and second rolls for handling the substrate media. The first roll applying pressure to the toner. After the application of pressure by the first roll, the toner remains partially unfused to the substrate media. The second roll subsequently engaging the pressed toner as the substrate media passes the second roll. The first roll and the second roll being disposed remotely from one another in a process handling direction of the substrate media. The method including the application of pressure to the unfused toner on the substrate media by a first roll. The method subsequently engages the pressed toner with a second roll for handling the substrate media. | 11-29-2012 |
| 20120308282 | IMAGING SYSTEM WITH SIMULTANEOUS DUPLEX PRESSURE FIXING - A system is provided for fixing first and second images on opposite sides of a piece of media. The system has an image forming section for forming at least the first image on the piece of media; and a pressure fixing section for fixing the images to the piece of media. The pressure fixing section has first and second rotating members that do not include a thermal energy source, the second member being located proximate the first member such that a gap exists between the first member and the second member, the gap being for receiving the piece of media, and a force applying device that applies force to at least one of the first member and the second member to apply pressure to the piece of media when the piece of media is located in the gap such that the first and second images are simultaneously fixed to the piece of media by the pressure. | 12-06-2012 |
| 20130230344 | APPARATUS AND SYSTEMS FOR HIGH PRESSURE FUSING ELECTROSTATIC OFFSET MITIGATION - A fusing apparatus includes a fusing roll and a backing roll that define a nip at which toner applied to marking material is fixed to paper under high pressure. A surface of the fusing roll includes a semi-conductive metal-oxide surface. Grounded conductive guides are arranged at the entrance and at the exit of the nip defined by the fusing roll and the backing roll. | 09-05-2013 |
