Abstract
An image sampling and color shift correction system in a multiple image forming apparatus forms a multiple image by providing a plurality of image output units along a transfer belt. An image control unit applies image data to the image output units. A pattern generator repeatedly generates a register shift measurement pattern in the main scanning direction and the sub-scanning direction of the respective image output units. The register shift measurement pattern is formed outside of the largest paper area. A sampling unit samples an image formed by the respective image output units at both sides of a paper on the transfer belt in the main scanning direction of the transfer belt. A processing unit takes data sampled by the sampling unit and processes the amount of register shift. A control unit controls the image output and image sampling correction.
