PURPOSE:To obtain an image whose color balance is good by providing a processing part for converting a means for correcting a color of an image data by an external command, forming a color image by its output, and forming an electrostatic latent image. CONSTITUTION:Signals Yi-Bi for showing each density value of yellow (Y), magenta (M), cyan (C) ad black (B) are inputted to a processing part by scanning a multi-color original. The processing part derives converted density values Y0-B0 by executing processing to an expressio by parameters alpha1-alpha4, beta1-beta4 converted by an external command, and stores them in memories My-Mb. In the expression, min(Yi-Ci) denotes a data for showing the minimum density value in three orignal color data Yi-Ci. An electrostatic charge image is formed by inputting this memory value to an exposing system, developed at every color, and transferred and fixed. In this way, an excellent multi-color image is obtained. |
