摘要： PROBLEM TO BE SOLVED: To improve a reduced transfer rate of an image formed on a rotating member to a medium.SOLUTION: A control unit of an image forming apparatus measures an initial dimension of an image for detection transferred onto a recording sheet (step S110). The control unit then performs image forming processing predetermined number of times, and measures the dimension of the image for detection transferred onto the recording sheet again (step S140). If an amount of change between the initial dimension and the measured dimension reaches a threshold (step S160:YES), the control unit 110 performs processing for scraping off an outer peripheral surface of an intermediate transfer belt (step S170).
