Abstract
Disclosed is a copying machine for forming a multicolored image, having a plurality of developing devices which contain toner of different colors, and a color image sensor for reading an original image. The copying machine judges each part of the original image whether to be a monochromatic area or a color area, from image data collected by the color image sensor. Then, the copying machine reproduces the monochromatic area by use of only one of the developing devices which contains black toner, and reproduces the color area by use of more than one of the developing devices which contain other color toner. Further, the copying machine detects a border area between the monochromatic area and the color area, and reproduces the border area by use of all the developing devices.
