Abstract
There are disclosed an image forming apparatus such as a digital copying machine and an image forming method. In the image forming apparatus and method, there are transformed supplied reference color image data into plural sample image data having color tones stepwisely different from each other by multiplying the reference color image data one by one by supplied plural color adjustment coefficients, and then, there are recorded plural sample images corresponding to the plural sample image data on a piece of recording paper. When the operator selects one of the plural sample images, a controller alters the supplied reference color image data into another reference color image data responsive to color adjustment coefficients of the selected one of the plural sample images.
