Abstract
The process of the invention determines whether toners of cyan (C), magenta (M), and yellow (Y) are all included in toner filled in a toner cartridge, based on color information of the toner read from a storage elementof the toner cartridge(Sand S). When the toners of all these colors are included in the toner cartridge, the process sets parameter values for a color image to control parameters (a fixation temperature T, a fixation pressure P, and a preliminary revolving frequency R) of a fixation process (S). When the toners of all these colors are not included in the toner cartridge, on the other hand, the process specifies formation of a monochromatic image and sets parameter values for the monochromatic image to the control parameters (S). This arrangement effectively ensures adequate formation of a color image and a monochromatic image and desirably prevents excessive deterioration of constituents of an image formation device.
