Abstract
A driving unit causes first and second light emitting units each to emit light in a time following a pulse duty with a light amount at a first light emission level for printing on an image portion in an image formable region of a photosensitive member according to input of print data, and causes the first and the second light emitting units each to emit light with a light amount at a second light emission level of weak light emission on a non-image portion in the image formable region of the photosensitive member, and an adjustment unit adjusts each of first, second, third, and fourth driving currents for a plurality of times in one job.
