摘要： It is intended to provide an image forming apparatus and image forming method capable of obtaining a comparatively high-quality image output even under a correction mode that gives preference to processing time required for correction, and capable of suppressing interruption of image formation to the utmost under operational condition such that internal temperature changes continuously. There are saved last five detections of positional shift quantity under first correction mode that gives preference to correction accuracy for each temperature band. Under second correction mode that gives preference to processing time required for correction, there is calculated a difference of a value actually obtained through measurement and an average value of data history belonging to a target temperature band (#7 through #9). Furthermore, the difference is multiplied by a reliability coefficient of main scanning direction and that of sub scanning direction, respectively, to determine correction quantity (#10, #11). Thereby, excessive change of correction quantity is prevented.

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of properly correcting a main scanning scale factor without degrading a required printing quality. SOLUTION: In a main scanning scale factor correcting process, for each of one or more correction points (at l-th, m-th, and n-th pixels) on each of lines along which scanning is carried out on a photosensitive drum 11 by laser light, the final bit data of pixel-division-modulated pixel data of a pixel immediately preceding each correction point is added as the leading bit data of the pixel-division-modulated pixel data of a pixel located at the correction point. The same processing as above is sequentially performed on pixel data of pixels located subsequently to the correction point to sequentially shift the pixel-division-modulated pixel data of pixels to pixel data of the respective following pixels by bit, to thereby generate pixel data of a new pixel to be added on each of lines. The generated pixel data of the new pixel is outputted in synchronism with an image clock of a fixed frequency. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： To make it possible to improve a printing speed. When printing a plurality of printing sheets 14 , it is possible to decrease the time for generating correction data by using a pair of correction data values to print the printing sheets 14 . Therefore, it is possible to decrease the time for printing each printing sheet 14 even compared to the case of a method for generating correction data for each printing sheet 14 . As a result, even when the number of sheets to be printed is large, it is possible to improve a printing speed. Moreover, when meandering states of the printing sheet 14 are changed, it is possible to prevent disorder of a printed image due to meandering of the printing sheet 14 for a long time by newly generating correction data. Furthermore, by generating (updating) only a part of correction data when newly generating the correction data, it is possible to decrease the time for generating the correction data and improve a printing speed.
