发明名称 Image correcting device, image forming apparatus, and image correcting method
摘要 A pattern generating unit generates correction patterns on a transfer belt. Detection sensors detect the correction patterns, and amounts of magnification correction, amounts of misregistration in the main- and the sub-scanning direction are calculated. The amount of skew between each of colors is then calculated, and a position where an image is divided and a direction for shifting a divided image are determined. Possible dividing-positions are also determined, and a calculated dividing position and each of the possible dividing positions are compared with one another. Then, a possible dividing position closest to the calculated dividing position is set as an actual dividing position.
