  • Image forming apparatus, image forming system, and image forming method for correcting amount of deviation in color of image
    Patent number: 11934133
    Abstract: An image forming apparatus includes an image forming device and circuitry. The image forming device forms an image. The circuitry corrects an amount of deviation based on a pattern formed by the image forming device, changes a magnification of the pattern, and calculates the amount of deviation based on the magnification.

  • Image forming apparatus and method for controlling image forming method
    Patent number: 8446443
    Abstract: An image forming apparatus includes: an optical-path deflecting unit that deflects optical paths of optical beams in one group out of two groups, the optical beams being provided in a sub-scanning direction at a predetermined pitch; a scanning unit that scans a surface to in a main scanning direction with the one group of which the optical paths have been deflected and another group of which the optical paths are not deflected; and a control unit that controls the optical-path deflecting unit to deflect optical paths of the optical beams in the one group so that irradiation positions of the optical beams in the one group and irradiation positions of the optical beams in the another group are alternately arranged at regular intervals.
