PURPOSE:To accurately and easily set the control target value of image density. CONSTITUTION:Image output devices 7-17 which output a color corresponding to a developing color used in the image output device in an incorporated pattern 27 for setting density on a recording paper and image readers 1-5 which read the image density of each color outputted on the recording paper are provided, and the target value of image density setting parameter of each color of the image output device is calculated based on a difference between read density and the target density. |
