摘要： The present invention is directed to the provision of an image forming apparatus capable of effectively preventing the formation of images related to illegal conducts by making provisions so that, even in situations where images can be formed based on image data outputted from any arbitrary image output apparatus, the image output apparatus which outputted the image data can be identified without fail. When image data is inputted from a portable image output apparatus, first it is checked whether identification information has been inputted together with the image data, then an image of an identification pattern is created, and image formation is performed based on image data obtained by attaching the image data of the identification pattern to the input image data. On the other hand, when image data is inputted from a fixed image output apparatus, first it is checked whether identification pattern data is included in a designated position in the image data, and then image formation is performed based on the input image data. The image thus formed by the digital copying machine contains the image of the identification pattern by which the image supply device that outputted the source image data is identified.

摘要： In conventional color digital copy machines, when copying in color mode, the polygon mirror of the laser beam scanner for black, which is driven at a higher speed than those of the other colors, is switched to a slower speed in conformity with the speed of the polygon mirrors for the other colors. However, a drawback of this structure is that, especially when switching from monochrome to color mode, the time required to obtain the first copy is lengthened, and the operating efficiency of copying is poor. In the present invention, when copying in color mode, the rotation speed of the polygon mirror of the laser scanner unit for black is not changed at all, but, by skipping certain mirror surfaces of the polygon mirror, and/or by skipping certain of a plurality of laser light sources, the scanning density of the laser scanner unit for black can be brought into conformity with that of the laser scanner units for the other colors.

摘要： The present invention is intended to reduce a f.theta. correction error by correcting an error of an object scanning speed which is produced because a reflecting point of a laser beam moves on a polygon mirror. In an inventive laser scanner, laser light emitted from a laser oscillator is condensed into a beam by a condenser lens at first. This laser beam is reflected by a polygon mirror rotated by a scanning section and is reflected again to a photoreceptor by a curved reflecting mirror. A curved profile of a reflecting plane of the curved reflecting mirror in the main scanning direction is formed so as to be asymmetrical on right and left bounding about a scanning center point. Thereby, variation of speed for scanning the curved reflecting mirror by the light reflected by the polygon mirror may be canceled by the curved reflecting mirror and a speed for scanning the object may be fixed almost at a predetermined speed.

摘要： An image forming apparatus is designed to compensate for voltage to be applied to an exposure lamp and a charger in accordance with changes in the density of a toner image formed on a photoreceptor that occur from its initial state to its final state after an image forming operation. More specifically, the density of a reference toner image is measured by a toner-density sensor. The amount of change in the density is measured beginning with its initial state by a subtracter, and the amount of compensation for the voltage required for obtaining the optimum image quality is found. By using these amounts of compensation as teaching data, learning is made as to the relationship between the amount of change in the density and the amount of compensation in a neurocomputer. Upon forming an image, the neurocomputer executes operations in accordance with the contents of the learning based on an inputted amount of change in density, and finds an appropriate amount of compensation. With this arrangement, it is possible to constantly obtain copied images having stable image quality, and to lower the cost of image forming apparatuses by reducing the number of parts used for the sensors or other devices.
