Abstract:
1. An image forming device for forming a multicolor image by superimposing a plurality of monochromatic images on a recording medium, the device comprising: an image carrying member carrying an image; a plurality of image forming units, each of the plurality of image forming units forming a monochromatic calibration image on the image carrying member; a measuring unit measuring at least one predetermined kind of information with respect to the monochromatic calibration image, thereby obtaining at least one data group of the at least one predetermined kind of information; a measurement-data storing unit that stores the at least one data group; an abnormal-data excluding unit excluding abnormal data from each of the at least one data group stored in the measurement-data storing unit, thereby obtaining normal data; and a color-registration correcting unit adjusting the plurality of image forming units based on the normal data, thereby correcting color registration errors among a plurality of monochromatic images.
