Abstract

A color image forming device produces a good image form, superior in color and gradation reproduction, and little over-enhancement in sharpness during generation duplicating. The device has an image processing parameter storage unit that stores parameters for processing which correspond to original document modes in respective processing blocks. An image processing parameter detector detects the original document mode, and provides the mode to the respective components as an original document mode directive TAG. When generation duplicating is designated, the generation duplicating mode corresponding to the set original document mode is set, and various parameter settings are indicated corresponding to the set generation duplicating mode in the image processing parameter storage unit. By such, the operation in each image processing module is converted to the set generation duplicating mode.
