Abstract
A method for forming a color image that allows a color image forming device to detect print chromaticity by an actually used print medium and automatically perform an optimal color balance adjustment in consideration of the chromaticity of the print medium. At a first step of the method, it is determined whether a feeder is selected for a subsequent printing operation. If selected, the process proceeds to a second step. If not selected, it is determined that the printing operation is not performed for some time and the process is completed without color balance adjustment. At the second step, a print medium for printing a test pattern is fed from the feeder selected for a subsequent printing operation, which is determined at the first step. A color sensor detects the chromaticity of the test pattern transferred and fused on the print medium, and the color balance is then adjusted.
