An optical writing device includes a light emission control unit configured to cause a light source to emit light based on a rotational position of a photosensitive element and pixel information making up a correction pattern to form an electrostatic latent image of the correction pattern on the photosensitive element, the correction pattern being formed across an entire circumference of the photosensitive element in a rotating direction; a reading signal acquiring unit configured to acquire reading signals resulting from reading the correction pattern, and generate, based on the reading signals, density variation information in which the rotational position and a density of the correction pattern are associated; and a correction value information generation control unit configured to generate information about correction to an amount of light emitted by the light source based on the density of the correction pattern to generate correction value information.
