PROBLEM TO BE SOLVED: To solve such a problem that image quality is deteriorated due to fluctuation in a feeding amount caused by feeding of a roll sheet with back tension applied thereto.SOLUTION: An image forming apparatus includes: a determination means 411 for determining whether a peak value of a PWM value exceeds a threshold value set in advance by inputting (monitoring) a PWM signal (PWM value) output from a PID control calculation unit 405; and a correction means 412 for outputting, when the PWM value is determined to have exceeded the peak value by the determination means 411, a signal to correct a target position given to a comparison calculation unit 403 to cause an increase in the feeding amount. |
