<p>PROBLEM TO BE SOLVED: To prevent occurrence of deviation as much as possible in a transferring position corresponding to the speed fluctuation of a driving system, regardless of variation in a range between respective image transferring points, in a color image forming device. SOLUTION: After the 1st image transferring point A and the 2nd image transferring point B are decided so that the range between these image transferring points A and B becomes an integral multiple of a reference length corresponding to speed fluctuation cycle of a driving system, the image transferring points C and D is respectively decided in order from the upstream side according to subsequent procedures. The 1st (up to 3rd) image tentative transferring point is decided, and the shortest transporting path, out of transporting paths from respective image transferring point of the 1st to 1-1st reaching the above tentative position, is determined with regard to the respective 1st to 1-1st image transferring point. Then, the position of the point is determined on the transporting path length of an integral multiple of the reference length, from the respective 1st to 1-1st image transferring point along the respective shortest transporting path, in the vicinity of the tentative position, and the position of the 1st image transferring point is decided based on the determined position of the point of 1-1 piece.</p> |
