The color image processor in accordance with the invention has a raster circuit 1 for receiving data about an image of multiple gray levels of plural colors, an UCR/BG circuit 2 for decomposing the image data received from the raster circuit 1 by the use of input Raster Operation codes according to color materials of plural colors, rasterizing the image data into a buffer memory 5, and generating black, and a binarization circuit 3 for binarizing raster data about each gray level and converting the data into data about images each having one gray level. If the aforementioned Raster Operation codes are other than Raster Operation codes having a base image, the raster output function, the UCR/BG functions, and the binarization function are performed simultaneously.
