ABSTRACT:
An optical scanning device is configured to identify a light-emitting unit at the start of writing on the basis of a sub-scanning resist displacement and selects a combination of four light-emitting units according to the light-emitting unit at the start of writing. The optical scanning device predicts the amount of deformation of pixel according to the combination and adjusts a light volume of light emission from a light-emitting unit to be corrected using the amount of deformation. Thereby, a pixel with an excellent shape quality can be constantly formed regardless of the combination of the light-emitting units and a pixel formed of multiple dots can be accurately and stably formed.
