摘要：
An exposure device includes a plurality of light emitting elements, a load, a first supplying unit and a second supplying unit. The first supplying unit supplies a driving current to one of (i) light emitting elements used to form an image among the plurality of light emitting elements and (ii) the load, in accordance with a modulation signal. The first supplying unit supplies a bias current to the other. The second supplying unit supplies the bias current to light emitting elements not used to form the image among the plurality of light emitting elements, regardless of the modulation signal.
