Optical scanning device and image forming apparatus

Abstract

An optical scanning device includes a scanning unit that performs scanning by disposing plural light emitting element groups, each of which includes plural light emitting elements arranged along a main scanning direction, along the main scanning direction so as to face a scanning target object and causing each of the light emitting element groups to emit light based on image information, and a drive unit that drives each of the light emitting element groups of the scanning unit for each scanning period, in which the drive unit divides the plural light emitting element groups into plural sets, and varies a timing of a non-scanning period set between the scanning periods in at least two sets of the light emitting element groups divided into the plural sets.
