When to perform subsidiary exposure before or after main exposure or concurrently therewith with a quantity of light corresponding to about 1/50 to 1/100 of the quantity of light of main exposure, an image forming apparatus according to the present invention can automatically set the standard conditions of subsidiary exposure in response to setting of the standard conditions of main exposure, and can set the optimal conditions of colors and intensity of subsidiary exposure in accordance with the amount of adjustment of gradation. Therefore, even when variations arise in the characteristics and processing conditions of a light-sensitive material or any desired gradation is chosen, natural and fine images can always be formed with no color balance distorted.
