摘要： A toner image fixing device realizes a stabilized fixing process by smoothly controlling a surface temperature of its heating roller, preventing peeling-off of a layer of the roller core. The toner image fixing device comprises a heating roller consisting of a core covered with a layer of, e.g., a silicon rubber, a heat lamp mounted in the heating roller and a pressure roller for pressing a sheet of paper against the heating roller. The toner image fixing device is provided with a temperature sensor for sensing a surface temperature of the heat roller and for operating the heater lamp at a preset ON-OFF ratio (e.g., 1:3) to elevate the heating roller surface temperature from a first preset value to a second preset value and thereafter to maintain it at the second preset temperature.

摘要： A transfer apparatus having a photoconductor drum for holding thereon an image formed by toner charged with a negative polarity and a transfer roller disposed opposite the photoconductor drum, in which paper is fed to an area where the photoconductor drum and the transfer roller face each other and the toner image on the photoconductor drum is transferred to the paper by using a unidirectional transfer electric field formed by the transfer roller. The transfer roller also serves as charge supply control device for supplying a charge to the toner held on the photoconductor drum to thereby substantially neutralize the charge of the toner while retaining the negative polarity of the toner.

摘要： Enabling to perform the pressurization release and the fixture release simultaneously by one action when taking out the fixing device from the image forming device for removing the jammed paper and the like. In a fixing device comprising a pressurization roll being pressurized by the act of a pressurization lever and a spring against a heat roll, a release lever is further mounted rotatably which comprises a cam for rotating the pressurization lever against the direction of force from the spring. On the release lever is mounted a connecting pin, and the connecting pin is linked to and rotates the fixing lever which is also mounted rotatably. The fixing lever is forced toward the fixing direction by a spring, wherein a fixing piece is inserted to a fixing slit of a mounting stage formed on the image forming device body for positioning thereto. By rotating the release lever, the pressurization lever could be rotated to the direction for releasing the pressure, and simultaneously, the fixing lever is linked thereto and rotated to the direction for releasing the fixing piece from the fixing slit, thereby performing the pressurization release and fixture release by a single operation.

摘要： The present invention is made to provide a pretransfer charging device, which allows (i) reduction of generation of discharge products such as ozone and nitroxide, (ii) excellent uniform charging, (iii) continuous stable charging for a long period of time, and (iv) restraint of distortion of a toner image. The pretransfer charging device includes (i) ion generation needles each provided face to face with an image carrier such as a photoconductor drum or an intermediating transfer belt, and (ii) a high-voltage power supply for applying a negative voltage to each of the ion generation needles. The voltage to be applied from the high-voltage power supply is not less than an ion production threshold voltage but is less than a corona discharge threshold voltage. With this, no corona discharge occurs but negative ions can be generated. This makes it possible to solve various problems caused due to the corona discharge.

摘要： A method of manufacturing a separator for a polymer electrolyte fuel cell in which the specific resistance is small, and the coefficient of thermal conductivity and the gas shielding property are high and have high strength. The sintering material comprises a phenol resin coated to the surface of a powder of carbon, and the plate is a metallic plate having plating on both surfaces. After the metallic plate is arranged in a mold provided with grooves, the sintering material is filled to both sides of the metallic plate, and then they are heated and sintered. The separator for a fuel cell becomes homogeneous, and, as a result, the gas shielding property rises with high strength, because phenol resin has been uniformly distributed in the sintering material. Moreover, because oxides are not generated on the surfaces of the separator by sintering, the specific resistance will be relatively small.

摘要： Ions are produced without causing any accompanying corona discharge by applying, to ion generation needles positioned so as not to contact a photoconductor drum, a voltage higher than or equal to an ion production threshold voltage and lower than a corona discharge threshold voltage. The photoconductor drum is charged by the ions produced. Accordingly, a charging device is provided which is capable of stable charging with high uniformity over a long period whilst reducing the production of ozone, nitrogen oxides, and other discharge byproducts.
