Abstract:
An image forming apparatus counts a number of sheets to be printed with a limited number of colorants or a limited amount of colorant using an other counter that is provided other than a color counter and a monochrome counter. The counter value of the other counter is adjusted using a weighting factor before being added to or subtracted from a counter value of the color counter or the monochrome counter.
