Abstract:
1. An image forming apparatus, comprising: a charge fee counter unit including: a counter processor configured to obtain selected one of: a total counter value of the color counter based on the first counter value and the third counter value; and a total counter value of the monochrome counter based on the second counter value and the third counter value, wherein the counter processor obtains the total counter value of the color counter by multiplying the third counter value with a weighting factor to generate a weighted third counter value and subtracting the weighted third counter value from the first counter value, the total counter value of the color counter being used for determination of a charge fee of the image forming apparatus based on a unit charge fee previously set for the full-color printing mode, and the counter processor obtains the total counter value of the monochrome counter by multiplying the third counter value with a weighting factor to generate a weighted third counter value and adding the weighted third counter value to the second counter value, the total counter value of the monochrome counter being used for determination of a charge fee of the image forming apparatus based on a unit charge fee previously set for the monochrome printing mode.
