摘要： An image forming apparatus for forming an image on an image forming body by scanning a plurality of modulated laser beams is disclosed. The apparatus is provided with a generator to generate a plurality of reference signals each with a differrent phase from other reference signals, a detector for detecting the difference of image density between two adjacent image pixels, combined modulator to generate a modulated laser beam by combining a selected laser beam, a selected reference signal and the image density. The detector classifies each pixel as one of an edge starting pixel, an edge ending pixel, and a non-edge pixel based on the value of image density difference relative to positive and negative threshold values. The selection of the laser beam and the reference signal is based on the image density difference detected by the detector and the class of the pixel.

摘要： In a toner image fixing device, there are provided an endless belt being looped up around a heating roller and a conveyance roller, a pressure roller for pressing a sheet having a toner image onto the heating roller with the endless belt intervening between the pressure roller and the heating roller. A sensor is disposed inside the loop of the belt so as to come in contact with the heating roller, for detecting the temperature of the heating roller. The fixing temperature for the toner image is controlled on the basis of the temperature of the heating roller detected by the sensor. A first nip region is formed on a pressing portion located between the heating roller and the fixing roller. A second nip region is formed between the belt and the fixing roller, continuing from the first nip region but without contacting the heating roller.

摘要： The invention provides a photoreceptor belt for forming a latent image on its imaging surface. The photoreceptor belt is stretched in the form of a loop around a plurality of rollers so as to be rotated for carrying a formed image. Both ends of the photoreceptor belt are bonded in the manner that the leading end in relation to the rotation direction is positioned inside than the trailing end in relation to the form of loop and the inner surface of the trailing end is superimposed on the outer surface of the leading end. Cleaning device for cleaning the imaging surface of the photoreceptor belt is disposed to have a cleaning direction opposite to the rotation direction of the photoreceptor belt. The photoreceptor belt is positioned to stop where the bonded ends of the belt are proximate to the corona charging device. The photoreceptor belt is then positioned to stop where the bonded ends of the belt are proximate to the fixing device when the next image formation is not conducted within a period of time after the previous image formation.
