Beschreibung
Zusammenfassung:	Provided is a color image forming apparatus which has photosensitive members and a light irradiation unit irradiating at least one of the photosensitive members, the color image forming apparatus including: a laser driving unit causing the light irradiation unit to emit light of a light amount at a first emission level for printing when exposing an image portion and to emit light of a light amount at a second emission level for weak emission when exposing a non-image portion; an acquiring unit acquiring information of remaining lifetime of each of the photosensitive members; a first light intensity adjusting unit adjusting a first drive current to emit light at the first emission level; and a second light intensity adjusting unit adjusting a second drive current to emit light at the second emission level, the second light intensity adjusting unit changing the second drive current in accordance with the information.
