Abstract
An image forming apparatus forming a full color image by plural color materials. An image of an original is color-separated so as to form a color separation signal, and the color separation signal is converted to a color signal corresponding to each color material. The color signal is color-corrected so as to correct a color mixing state of the plural color materials, and a color image is formed by the corrected color signal. A test image of single color is formed, and a density of the test image is detected. Control is performed on a correcting condition for color-correcting the color signed based on the detected density. The correction to the color signal is delayed until toner is supplemented to the developing device.
