ABSTRACT:
In an image forming apparatus provided with a rotary type image developing apparatus, during monochrome print job processing, it is judged whether the amount of toner remaining in the developing chamber of the black developer unit is equal to or less than a predetermined amount M. If the judgement is affirmative, (i) the monochrome print job is suspended, (ii) the rotary rack is rotated to stop the black developer unit at the toner supply position temporarily, and is moved to the developing position again, and (iii) the monochrome print job is resumed. With the stated structure, the toner can be steadily supplied even when the amount of toner remaining in the developing chamber gets low during executing monochrome print jobs.
