Claim Text:
1. An optical writing device that forms an electrostatic latent image on a photoreceptor, the optical writing device comprising: a pixel-information acquiring unit that a tilt correcting unit that generates a tilt correction signal specifying a main scanning line from which the pixel information is read out of the storage medium and inputted to a light source, which exposes the photoreceptor to light, in order to correct a tilt of the electrostatic latent image formed on the photoreceptor; a position correcting unit that generates a position correction signal specifying a timing to input the pixel information to the light source in order to correct a position of the electrostatic latent image formed on the photoreceptor in a sub-scanning direction; and a pixel-information-input control unit that controls input of the pixel information from the storage medium to the light source in response to the tilt correction signal and the position correction signal, wherein the pixel-information-input control unit adjusts input timing of the pixel-information to the light source, by adjusting the input timing of the pixel-information to the storage medium; and the position correction unit adjusts input timing of the pixel-information to the light source, by adjusting the input timing from the storage medium to the light source independently of the input timing of the pixel-information to the storage medium.
