Abstract
An exposure device for exposing a photoreceptor, includes: data electrodes disposed for each of a plurality of columns parallel to a moving direction of the photoreceptor; selected electrodes disposed for each of a plurality of rows perpendicular to each of the data electrodes; light emitting element arrays including light emitting elements disposed near intersection points between the data electrodes and the selected electrodes in intersections between the data electrodes and the selected electrodes, the light emitting elements being linearly arrayed; a driving signal output circuit for generating a driving signal based on an image signal to supply the driving signal to the light emitting element arrays; and a column selection unit for switching the light emitting element arrays to be selected based on a lighting situation of each of the light emitting elements of each of the light emitting element arrays.
