摘要： In an image forming apparatus in which a visual image on a photosensitive drum is developed with columnar toner, and the developed toner image is transferred from the photosensitive drum to an intermediate transfer belt, a moving speed of the photosensitive drum and a moving speed of the intermediate transfer belt are different at a contact position (transfer nip section) where the photosensitive drum and the intermediate transfer belt are in contact. With this arrangement, toner scattering, nonuniform image etc. can be reduced in the image forming apparatus, in which the development is carried out with columnar toner.

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： To improve the fixing ability in the fixing device, and simultaneously prevent hot offset occurring during continuous fixing process. In the interior of a cored bar of a heat roll is mounted a heater lamp, and by controlling the power supplied to said heater lamp, heat roll is maintained at a first set temperature enabling heat fix. To this heater lamp is pressed a pressurization roll formed by covering a cover layer to a cored bar, which forms a fixing device. The heat roll is controlled and maintained at the first set temperature T.sub.1 at the initial fixing process, and when performing a continuous fixing process, it is switched and controlled to a second set temperature T.sub.2 lower than the first set temperature but enabling fixing. Thereby, the fixing ability could be maintained well, preventing hot offset.

摘要： A developing device includes a developing roller and a toner charging roller. The toner charging roller has (a) a metallic layer which induces its electrons by receiving light irradiation, and (b) an ultraviolet irradiater which irradiates ultraviolet to the metallic layer. The toner charging roller gives the electrons to toner, so that the toner on the developing roller is charged. There is a space between the toner charging roller and the developing roller, and a grid electrode which controls a flow of the electrons is provided in the space. Thus, mechanical/thermal load given to the toner or the toner charging roller can be reduced, so that it is possible to prevent deterioration of toner and the device.
