摘要：
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 having a value determined based on a number of colors of colorant or an amount of colorant that is used for printing in the economical printing mode, before being added to a counter value of the color counter or the monochrome counter.
