Abstract
An automatic document feeder includes a controller that compares an input original length that is received from a main operating unit and an actual original length that is calculated based on a detection result from a registration sensor arranged, on a conveying path, downstream of a separation feeding unit. The controller sets, when a result of the comparison indicates that the input original length and the actual original length are not equal, a larger value between the input original length and the actual original length as a jam determining value. The controller controls a jam detection based on the set jam determining value.
