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.

摘要： A conventional image forming device having a plurality of image optical scanning recording sections has had a drawback of being incapable of correcting printing positions of the image optical scanning recording sections with high precision by using a small-scale circuit. In the case of an image forming device of the present invention, a variable clock generator 114 having a voltage control oscillator (VCO) 114a is provided therein as reference clock signal generating means of laser control system of each of image optical scanning recording sections (LSU) for cyan, yellow, and magenta. By so doing, during an invalid printing period prior to a valid printing period, frequencies of the reference clock signals of the LSUs for cyan, yellow, and magenta are adjusted in accordance with offsets of printing start positions of these LSUs with respect to that of the LSU for black, so that printing offsets are eliminated. As a result, the printing start positions are made to coincide with each other with high precision even with a small-scale circuit.

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.
