An exposure device includes a reference current generating unit generating a reference current for each image of respective colors, a photoelectric current generating unit generating a photoelectric current in response to a light amount of the light emitting element, a driving unit driving the light emitting element, a first controller, a drive voltage holding unit holding a drive voltage given to the driving unit, a second controller controlling the driving unit based on the drive voltage held, a comparison current generating unit generates a comparison current, a difference current generating unit generating a difference current, of each color, corresponding to a difference between the reference current of each color and the comparison current. The first controller compares a value obtained by adding the difference current of each color to the photoelectric current with the comparison current to control the driving unit so that the photoelectric current becomes the reference current.

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.

An exposure device includes plural light-emitting elements, a light amount detection unit, a controller, plural holding units and a connection unit. The controller sequentially determines control values of the light-emitting elements based on comparison between the light amounts detected by the light amount detection unit and a predetermined reference value. The holding units are provided for the light-emitting elements, respectively. Each holding unit holds a control voltage of the controller. When the controller is to sequentially determine control values of a part of the plurality of light-emitting elements, the connection units connects the controller and the holding units corresponding to one or more light-emitting elements for which control values are determined earliest among the part of the plural light-emitting elements, before the controller determines the control values of the one or more light-emitting elements.
