摘要： In a transfer method of a colored image, the process speed is initially properly set in accordance with the size of a copy paper sheet to be used. The transfer voltage is then changed in accordance with the process speed. After these processes, a colored toner image formed on a photoconductor is first transferred onto an intermediate transfer medium and then further transferred onto the copy paper sheet.

摘要： Electron generating devices and LED arrays are arranged in a surrounding area of a photosensitive drum. The electron generating devices are located downstream of a cleaner and upstream of a developing unit with respect to a turning direction of the photosensitive drum with a specific gap between the electron generating devices and a surface of the photosensitive drum. The LED arrays are disposed against outer ends of the electron generating devices opposite to inner ends thereof facing the photosensitive drum. When activated by a driving circuit according to image information, individual LED elements of the LED arrays emit light, causing the electron generating devices to emit electrons in a pattern corresponding to the image information. The electrons emitted from the electron generating devices produce more electrons due to an electron avalanche phenomenon before reaching the photosensitive drum, eventually forming an electrostatic latent image on the surface of the photosensitive drum.

摘要： A developing device prevents deterioration of toner, i.e., prevent the toner from being damaged, or fused onto the blade, to realize a more reliable developing operation. In the developing device, an electron emitting section is provided onto the toner regulation blade in which apertures (151) are formed, wherein each of the apertures (151) is formed by electroforming to have an inner surface curved convexly to be widened outwardly to the side irradiated with an ultraviolet ray (shape A). Further, a photoelectric surface (152) is laminated on the surface of the electron emitting section with the apertures (151). With an application of ultraviolet ray onto the electron emitting section, the resulting photoelectrons as emitted from the photoelectric surface (152) are guided to the toner through the apertures (151). Here, for the aperture (151) of the shape A, a larger amount of electrons can be guided to the toner than the apertures in other shapes (B to E).

摘要： Light emitted from an entire surface of a light source is passed selectively through a liquid crystal shutter. The shutter can be controlled to open/close on a pixel basis in response to image data and then selectively passed light is converted into light having a specified wavelength by a nonlinear optical element before impinging on a metal film. The metal film induces and emits its own electrons and forms an electrostatic latent image directly on a dielectric film.

摘要： Toner attracted onto an electronic latent image formed on the surface of a photosensitive drum is transferred onto a transfer sheet, using a transfer bias from a transfer bias roller. A transfer belt for transporting the transfer sheet includes an anisotropic conductive layer composed of conductive members and an insulating member. The anisotropic conductive layer is conductive only in the thickness direction thereof and insulating in the other directions. This makes it possible to offer a transfer device that can prevent a transfer electric field from spreading and toner from being projected, and that boasts excellent sheet transportability.

摘要： A fixing method for fixing an unfixed toner image formed on a recording material by transporting the recording material to a contact portion between a fixing roller and a pressurizing mechanism for pressurizing the surface of the fixing roller is arranged such that the fixing roller surface temperature and the pressurizing mechanism surface temperature at the contact portion while the recording material is being transported therethrough are controlled to fall within a non-offset region in which a sufficient fixing strength for fixing toner onto the recording material can be ensured without generating a high temperature offset, said non-offset region being defined by a critical border line obtained from a function of a fixing roller surface temperature and a pressurizing mechanism surface temperature. According to the described fixing method, an occurrence of an offset can be prevented without an application of an oil, and a toner fixing inferior can be prevented.
