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： An electrophotographic toner is prepared by using a binder resin having an acid value of 5 to 15 mgKOH/g, a salicylic metal complex, a colorant, and a releasing agent. In the preparation determination for the third root distribution of a light emission voltage by helium atmospheric pressure microwave induction plasmas for carbon atoms derived from the binder resin and metal atoms derived from the salicylic metal complex is made based on a value measured by a micro-particle measuring apparatus including a normal pressure or atmospheric pressure space, a capillary tube inserted at one end in the space, a microwave source, a cavity, a quartz tubular reactor, a discharge means, an analyses means, and a signal detection portion. The absolute deviation showing the scattering of approximate straight lines approximated by a least squares method is controlled to be 0.08 or less.
