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 cartridge40, based on color information of the toner read from a storage element50of the toner cartridge40(S100and S110). When the toners of all these colors are included in the toner cartridge40, 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 (S120). When the toners of all these colors are not included in the toner cartridge40, on the other hand, the process specifies formation of a monochromatic image and sets parameter values for the monochromatic image to the control parameters (S130). 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.
