<P>PROBLEM TO BE SOLVED: To provide a correction system of semiconductor laser array light equalizing the emitted light quantity in printing operation with that in light quantity adjustment. Ž<P>SOLUTION: In control of correction of the light quantity of the semiconductor laser array with a plurality of light sources arrayed on one chip, when the light quantities of respective light sources of the semiconductor laser array are sequentially corrected using one light quantity detecting means, supply of an emission current and a bias current to each light source not corrected in light quantity is cut off and the light emission current and the bias current are supplied only to the light source to be corrected in light quantity.
