Optical scanning device and image forming apparatus

Abstract

An optical scanning device includes: a scanner that includes multiple light-emitting element sets, the multiple light-emitting element sets being arranged in a main scanning direction so as to face a subject to be scanned and being each constituted by multiple light-emitting elements arranged in the main scanning direction, and that scans the subject by causing each of the multiple light-emitting element sets to emit light based on image information; a driver that drives each of the multiple light-emitting element sets for each scanning period; and a discard-current generator that generates a discard current which is to flow from the driver during a non-scanning period which is set between the scanning periods, the discard current being different from a current to flow to each of the multiple light-emitting element sets, and that also controls the generated discard current.
