Title: Image forming device
Inventor: KIMURA KUNIYASU
IPC: G03G21/14
Filed: 2000-05-25
Abstract: PROBLEM TO BE SOLVED: To form a high quality color image on a recording material which is carried by a transfer belt, by reducing displacements between colors resulting from a variation in speed caused by ununiform thickness of the transfer belt. SOLUTION: Y, M, C, and K color resist patterns are formed on a recording material and set in the scanner of the device to be read. An amount of displacement of each color, which results from a variation in speed caused by ununiform thickness of the transfer belt, is detected over the entire length of the endless belt and the amount is stored. At the time of image formation, a position on which the recording material is placed on the transfer belt is determined based on, for example, the detection of, the leading end of the recording material by a sheet-leading-end sensor. An average amount of displacement of each color pattern of the recording material which corresponds to one page is obtained from data on the placement position, the size of the recording material, and the amount of the displacement.  Then, for example, delay which is carried out by a Y delay part is controlled to delay the timing of the start of exposure in a sub-scanning direction. Thus, the average amount of the Y displacement approaches that of the K displacement. An amount of correction is determined so that the average amounts of the color slippage of the Y and K of the one page are finally eliminated. This process is also performed for the M and C.
