ABSTRACT:
At least one light emission array includes a plurality of light emitting elements arrayed in a first direction. Each of the light emitting elements is an organic electroluminescence element. A monitor quantitatively monitors a light emitting state of at least one of the light emitting elements to obtain a monitored amount. A comparator compares the monitored amount and a reference amount. A controller performs a constant current control with respect to at least one of the light emitting elements in accordance with a result of the comparison performed by the comparator.
