Abstract
An optical writing control device and method are provided, for controlling light emission of a plurality of light sources to form an electrostatic latent image on a photosensitive element, the light sources including a plurality of light emitting elements disposed in a line and classified into a plurality of groups, including frequency converter circuitry configured to acquire image information to be formed as the electrostatic latent image; and a light source controller configured to control the plurality of light sources based on pixel information generated from the acquired image information, wherein the light source controller is further configured to control the light emission of the plurality of light sources by classifying the light emitting elements into the plurality of groups, and shifting a timing of light emission from one group of the plurality of groups to a next group of the plurality of groups, and determine a common illuminating period for the light emitting elements of at least one light source of the plurality of light sources based on the shifted timing of light emission among the plurality of groups.
