  • Image forming apparatus for correcting density unevenness
    Patent number: 10620578
    Abstract: An image forming apparatus includes an image forming device to form an image on an image bearer and circuitry configured to accept, from a user, an input of a density level selected from a plurality of different density levels and control an image forming condition under which the image forming device forms the image. The circuitry is configured to correct density unevenness of the image formed on the image bearer by the image forming device and correct the density unevenness of the image at the density level accepted. The density unevenness is unevenness appearing in a main scanning direction orthogonal to a direction of conveyance of the image bearer during image formation.

  • Image processing apparatus and image processing method
    Patent number: 8749822
    Abstract: An image processing apparatus includes a first determination part that determines whether an image in which a feature image is embedded is to be modified when the image is printed, based on the image and a state of the image processing apparatus; and a second determination part that determines a condition for avoiding the modification determined by the first determination part.
