Claim:
1. An image forming apparatus comprising: a plurality of exposure units, each of the exposure units including a plurality of light emitting elements arranged in a main scanning direction; a calculating unit to, with respect to each of the exposure units, calculate a pre-charge period that is a period during which a pre-charge is performed on at least one of the light emitting elements included in a corresponding exposure unit; and an emission control unit to, with respect to each of the plurality of exposure units, cause the plurality of light emitting elements included in a corresponding one of the plurality of exposure units to emit light such that a pre-charge period of each of the plurality of exposure units is shifted with respect to pre-charge periods of remaining ones of the plurality of exposure units, wherein a length of a pre-charge period of each of the plurality of exposure units varies with respect to a length of pre-charge periods of remaining ones of the plurality of exposure units.
