摘要：
An exposure head includes: a first light emitting device group including light emitting devices disposed at different positions in a direction perpendicular or approximately perpendicular to a moving direction of an exposed side; a second light emitting device group disposed in the moving direction of the exposed side with respect to the first light emitting device group; an imaging optical system imaging light from the light emitting devices to expose the exposed side; and a control unit allowing one light emitting device group out of either the first light emitting device group or the second light emitting device group to emit light on the basis of a driving signal.
