IMAGE FORMING SYSTEM, IMAGE FORMING APPARATUS AND CHARGE CALCULATION METHOD

摘要

PROBLEM TO BE SOLVED: To change charge calculation at a point of time when a job satisfies a predetermined condition while the job is in execution.

SOLUTION: This image forming apparatus 1 includes a job execution control unit 36 which controls the execution of the job; a storage unit 22 which stores a charge map for performing charge calculation according to the execution of the job; a charge calculation unit 37 which performs charge calculation in reference to the charge map stored in the storage unit 22 according to the execution of the job by the job execution control unit 36; and a charge map switching part 37a which changes a charge map referred to by the calculation unit 37 when the execution state of the job by the job execution control unit 36 satisfies a predetermined condition.
