PURPOSE:To easily execute a color balance adjustment, even for different photosensitive materials, by controlling an insertion quantity of a color filter by a table corresponding to a selected photosensitive material. CONSTITUTION:When the copy start switch of a console panel is turned on, the arithmetic operation of a filter and its insertion quantity, and the arithmetic operation of a diaphragm quantity are executed during the timer time, and when its timer time is elapsed, a first filter plate 61 is controlled, based on the arithmetic operation, and when this control is completed, a second filter plate 62 is controlled, based on the same arithmetic operation, and when its control is completed, a diaphragm 63 is controlled, based on the arithmetic operation. Thereafter, a light source starts an exposure scan. Also, the table of a data of a density variation characteristic is prepared in accordance with each color of each photosensitive material, and when a specified photosensitive material contained therein is selected, the corresponding table is selected, a color density variation quantity by operating a button in case of adjusting a hue becomes common to each photosensitive material.
