Abstract:
1. A color image forming apparatus which has a light irradiation unit irradiating a charged photosensitive member with light to form an electrostatic latent image, the color image forming apparatus comprising: a light emitting element emitting light and provided in the light irradiation unit; a laser driving unit causing the light emitting element to emit light in accordance with an input of print data, the laser driving unit causing the light emitting element to emit light of a light amount at a first emission level for visualizing a toner image onto a first area where the toner image is to be visualized on the charged photosensitive member and to emit light of a light amount at a second emission level for weak emission onto a second area where the toner is not to be adhered to the charged photosensitive member, wherein the laser driving unit supplies a drive current for the first emission level to the light emitting element so that the light emitting element emits light of the light amount at the first emission level, and the laser driving unit supplies a drive current for the second emission level to the light emitting element so that the light emitting element emits light of the light amount at the second emission level; an acquiring unit acquiring information of an integrated number of rotations of the photosensitive member; and a drive current adjusting unit adjusting the drive current for the second emission level, the drive current adjusting unit changing a magnitude of the drive current for the second emission level in accordance with the information of the integrated number of rotations of the photosensitive member acquired by the acquiring unit.
