Abstract
An optical writing controller controls emission of a light source device including multiple light emitting element rows each constituted by multiple light emitting elements arranged in a sub-scanning direction to form an electrostatic latent image on a photoconductor. The optical writing controller includes an image information acquisition unit to acquire image information on an image to be formed as the electrostatic latent image; a light source control unit to sequentially control emission of the multiple light emitting elements on the basis of information on pixels generated on the basis of the acquired image information; an error information acquisition unit to acquire information indicating an error of a direction in which the light emitting elements are arranged with respect to the sub-scanning direction; and an adjustment value generation unit to generate an adjustment value for adjusting a light quantity of each light emitting element on the basis of the error.
