摘要： An optical writing control device includes a light emission control unit that controls light emission of a light source to exposes a photosensitive element. The light emission control unit is configured to draw two patterns as patterns for correction used to correct a transfer position of a developer image obtained by developing an electrostatic latent image formed on the photosensitive element, the two patterns including a narrow width pattern where a width of the pattern corresponds to a width of a detection area of a sensor that detects the patterns, in the main-scanning direction, and a wide width pattern having a wider width than the narrow width pattern, and control the light emission, after calculation of a correction value based on a detection signal of the wide width pattern is properly completed, in a manner where the narrow width pattern is drawn upon the calculation of the correction value.
