Abstract
An image forming device capable of reducing transfer errors of paper even when the transfer amount of paper cannot be detected accurately. The image forming device is provided with a motion sensor, and calculates the transfer amount of paper using signals output by the motion sensor. It is determined whether or not the transfer amount is within a predetermined normal range. If it is determined that the transfer amount is within the normal range, a paper transfer amount control value is set to the calculated transfer amount, while if it is determined that the transfer amount is outside the range, the paper transfer amount control value is set to a preliminarily set standard transfer amount. The image forming device controls the transfer of paper based on the above paper transfer amount control value.
