Provided is an optical scanning head including plural light-emitting element arrays that are arranged along a scanning direction, each of which includes plural light-emitting elements, a light-emitting control unit that outputs a light-emitting timing signal generated based on image information to each light-emitting element of the plural light-emitting element arrays to control light emission of the light-emitting element, a storage unit that is common to the plural light-emitting element arrays and stores a correction value of a light intensity variation due to an arrival time difference between the light-emitting timing signals to the plural light-emitting elements, and a correction unit that corrects the light-emitting timing signal based on the correction value.
