| 20090169271 | ELECTRONIC PHOTOGRAPH PRINTER - An electronic photograph printer is provided for elastically biasing the developer apparatus having the photosensitive drum by the pressing mechanism and for pressing the developer roll onto the photosensitive drum. In this configuration, quality in the developed image can be ensured by the trackable movement of the developer roll relative to the photosensitive drum in the electronic photograph printer. In addition, adjustable range for positioning the developer roll and operability and maintainability within the developer apparatus can be achieved. | 07-02-2009 |
| 20090185841 | TONER-FIXER APPARATUS AND ELECTRONIC PHOTOGRAPH PRINTER - A toner-fixer apparatus | 07-23-2009 |
| 20100086336 | TONER FIXING APPARATUS AND ELECTROPHOTOGRAPHIC PRINTING DEVICE - A toner fixing apparatus characterized by provision of a provisional fixing portion provided with a provisional fixing component having an infrared heater irradiating infrared radiation onto a printed surface of the web and a main fixing portion provided downstream in the web flow in the provisional fixing portion and nipping the web with heat rollers performing a main fixing operation or having a plurality of main fixing units. According to this invention, a toner fixing apparatus and an electrophotographic printing device including the toner fixing apparatus are provided which display excellent fixing properties during multicolor image formation, excellent heating efficiency and excellent economy with respect to installation space. | 04-08-2010 |
| 20110026991 | ELECTROPHOTOGRAPHIC PRINTER - An electrophotographic printer is configured such that an infrared heater is installed at a position between a plurality of electrophotographic print units installed in of the flow direction of a recording material, and a part (an inter-unit extension part) situated between print units of the recording material is irradiated with infrared light from the infrared heater to perform a partial evaporative removal of a carrier liquid of the recording material and a partial fixing of a toner. | 02-03-2011 |

| 20090169238 | Electrophotographic Printer - An electrophotographic printer is provided which can be cleaned so as to meet the requirement for high speed printing on a continuous web of paper as the printing medium and to make minimum the amount of toner that remains on the surface of a rotating transfer roller even in high-speed production. | 07-02-2009 |
| 20090169254 | ELECTROPHOTOGRAPHIC PRINTER - An electrophotographic printer in which a photoconductor drum and a transfer drum can be supported in a simple component construction and in the makeup free from misalignment and development of thrust load. To this end, an electrophotographic printer comprising a photoconductor drum ( | 07-02-2009 |
| 20090169278 | Photoconductor Drum Cleaning Apparatus in an Electrophotographic Printer - A photoconductor drum cleaning apparatus in an electrophotographic printer is disclosed which is simple in makeup, which allows a wiping roll to be rotated to follow rotation of the photoconductor drum is rotated and to be serviced for a prolonged life and is capable of performing an improved cleaning operation. To this end, the photoconductor drum | 07-02-2009 |
| 20100124431 | ELECTROPHOTOGRAPHIC PRINTER - To meet with the requirement for high-speed printing with continuous paper used as its recording medium and to better clean a transfer roller surface in high-speed production as well, an electrophotographic printer is provided comprising: a carrier liquid supply unit | 05-20-2010 |
| 20100196055 | WET TYPE DEVELOPING APPARATUS - A wet type developing apparatus is disclosed which can eliminate the need to provide a separately built cleansing unit and, moreover, makes it unnecessary to dismount a developer supply unit for its cleansing operation and to perform its subsequent re-mounting operation. | 08-05-2010 |
| 20100284709 | Wet Type Electrophotographic Printer - To remove a surplus carrier liquid after development on the surface of a photoconductor drum to obtain homogeneous printed images without being affected by an error in rotational accuracy of such as a carrier liquid removing roller, there is provided a wet type electrophotographic printer in which the carrier liquid removing roller | 11-11-2010 |
| 20110013942 | Wet Type Developing Apparatus - A wet type developing apparatus in which a liquid developer is fed onto a developing roller from a liquid developer supply roller immersed in the developing liquid within a liquid developer tank and an electrostatic latent image formed on a photoconductor drum is developed into a toner image by said developing roller is improved to enable the liquid developer to be kept fed at an appropriate amount of feed from the liquid developer supply roller onto the developing roller without air residual in the surface region of the liquid developer supply roller. The improvement comprises a partition plate disposed generally under the liquid developer supply roller within the liquid developer tank for partitioning the liquid developer tank into two in the direction of rotation of the liquid developer supply roller, the partition plate having its upper end juxtaposed with a peripheral surface of the liquid developer supply roller over its total axial length across a gap spacing between 0.05 and 0.5 mm. | 01-20-2011 |
