A color image processing apparatus where in the event of reproducing an image which has undergone an adaptive character-area processing with toner of four colors, the optimum filtering and halftone processing are performed depending upon the colors of the toner so that a high-grade color image which contains solid black characters having no blur can be obtained. For color image data of various colors including yellow, magenta, cyan and black for toner development, a coefficient of a filtering circuit (6) and a characteristic of a halftone processing circuit (8) are changed so as to practice a filtering and halftone processing for a character mode to the color image data of black, or practice the filtering and halftone processing for a photograph mode to the color image data other than black. In this way, even if a color photograph image contains images of black solid characters, the color photograph image can be reproduced into multi-leveled gradation, and moreover, the black solid character images contained therein can be reproduced having no blur with color with high resolution.
