Abstract
An image forming apparatus includes an image forming device to form an image on an image bearer based on a prescribed image-forming condition, and circuitry to change the prescribed image-forming condition and correct image-density unevenness in an image-width direction orthogonal to an image conveyance direction of the image bearer. In the image forming apparatus, the circuitry calculates a corrective value of the prescribed image-forming condition for each one of positions in the image-width direction, based on unevenness-in-density corrective values for the multiple positions in the image-width direction and relational values indicating a relation between the multiple unevenness-in-density corrective values and the corrective value of the prescribed image-forming condition, and the circuitry corrects the image-density unevenness in the image-width direction based on the corrective value of the prescribed image-forming condition. In the image forming apparatus, the multiple relational values correspond to portions in the image-width direction.
