Abstract
A color image forming apparatus including image forming portions for respective color components of yellow, magenta, cyan, and black. It can be set whether a discriminating function of discriminating whether an original image is a color image or a monochromatic image is used. If the use of the discriminating function is set, a preparatory operation of forming the image in a full-color recording mode is performed before obtaining a result of the discrimination. When the result of the discrimination is monochrome, the image formation in a monochrome recording mode is executed after a shift from the full-color recording mode to the monochrome recording mode. If configured to perform the preparatory operation of forming the image in the monochrome recording mode before obtaining the result of the discrimination, when the result of the discrimination is color, the image formation in the full-color recording mode is executed after a shift from the monochrome recording mode to the full-color recording mode.
