摘要： When a grounded conductive roller touches a transfer drum through a transfer material while a voltage is applied to a conductor layer, charges having a polarity opposite to the polarity of the voltage applied to the conductor layer are generated over the transfer material, thereby making it possible to attract the transfer material to the dielectric layer. Since the voltage is applied to the conductor layer, the electrostatic attraction of the transfer material and the toner transfer can be carried out using a single power source. Moreover, since the attraction of the transfer material and the toner transfer are carried out by the charge injection, a lower voltage can be used. Thus, the voltage can be readily controlled while reducing the ozone emission to a relatively low level. Furthermore, since the toner transfer and electrostatic attraction of the transfer material can be carried out using a single power source, the apparatus can be downsized and less expensive. In addition, when a semiconductor layer is made of a solid elastic body, a high-quality transferred toner image can be obtained without image quality deterioration.
摘要翻译：当接地的导电辊通过转印材料接触传送鼓，同时向导体层施加电压时，在转印材料上产生具有与施加到导体层的电压的极性相反的极性的电荷，从而使其成为可能以将转印材料吸引到介电层。由于向导体层施加电压，所以可以使用单个电源来进行转印材料的静电吸引和调色剂转印。此外，由于转印材料和调色剂转印的吸引是通过电荷注入进行的，所以可以使用较低的电压。因此，可以容易地控制电压，同时将臭氧发射降低到相对低的水平。此外，由于可以使用单个电源来进行转印材料的调色剂转印和静电吸引，所以可以将装置小型化并且成本更低。此外，当半导体层由固体弹性体制成时，可以获得高质量的转印调色剂图像而没有图像质量劣化。

摘要： An image forming apparatus is provided with a photosensitive drum on whose surface a toner image is formed, and image formation is carried out by transferring the toner image onto a transfer material such as paper or OHP sheet which is caused to electrostatically adhere to a surface of a transfer drum while being guided to the photosensitive drum. Alternatively, the toner image formed on the photosensitive drum may be once transferred onto an intermediate transfer drum, then transferred from the intermediate transfer drum onto the transfer material. In the image forming apparatus, a light projecting device for projecting light onto the photosensitive drum is provided on an upstream side to a toner image transfer position and on a downstream side to a development position on the photosensitive drum. Execution and suspension of the light projecting operation of the light projecting device is controlled depending on a toner type.

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： 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.
