Abstract
An optical writing device forms an electrostatic latent image and includes a pixel-information acquiring unit that acquires pixel information and stores the acquired pixel information in a storage medium with respect to each main scanning line; a tilt correcting unit that generates a tilt correction signal specifying a main scanning line from which the pixel information to be input to a light source is read out from the storage medium in order to correct a tilt of the electrostatic latent image; 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; 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.
