  • Patent number: 5550625
    Abstract: A color image forming apparatus for forming a color image by transferring images of different colors on a recording medium in a multi-transfer mode. The color image forming apparatus includes a plurality of image forming units for successively forming color images of different colors according to image information, a transfer/transport unit for transporting different color images formed by the image forming units in a state that the color images are successively transferred thereon, a detecting unit for detecting patterns used for detecting an out-of-registration of the color images formed on the transfer/transport unit by the image forming units, and a correcting unit for correcting positions of the color images to be transferred on the transfer/transport unit according to data signal output from the detecting unit.
