摘要:
An optical writing device (111) that forms an electrostatic latent image on a photoreceptor (109). The device includes a pixel-information acquiring unit (123), a line-pixel-information storage unit (122) that stores the acquired pixel information corresponding to a plurality of lines for each main scanning line, a light source device (281) that exposes the photoreceptor with a period corresponding to an N-fold sub-scanning direction resolution of the pixel information, a positional-shift-information storage unit (124) that stores a positional shift information, a sub-line counting unit (121c) that counts a sub-line period, a reading-line selecting unit (121e) that performs N times of selection that determines which main scanning line is selected as the line from which the pixel information is read out, on the basis of a calculated value from the counted value of the sub-line period and the positional shift information, and a pixel-information reading unit (121d).
