Abstract
An exposure device includes a plate member, a plurality of light-emitting elements, and an optical system. The plate member extends in both a first direction and a second direction intersecting with the first direction. The light-emitting elements are disposed on the plate member side by side in the first direction. The light-emitting elements emit respective light beams in the second direction. The optical system is disposed on the plate member and faces the light-emitting elements in the second direction. The optical system performs imaging of the light beams emitted by the respective light-emitting elements.
