An original carrying apparatus includes a separation unit for separating one original from a plurality of stacked originals, a carrying roller for carrying the original separated by the separation unit, a carrying belt for receiving the original carried by the carrying roller, and carrying the originals in a state where the plurality of originals are being held, wherein the carrying belt carries the original such that the original passes through an exposure position at a first speed, and a control unit for performing control to set an interval between the two originals carried by the carrying belt to be a first distance. The control unit performs the control to set the interval between the two originals to be the first distance after setting it to be a second distance shorter than the first distance, by using the carrying roller. Further, the control unit accelerates the carrying belt up to a second speed, decelerates the second speed to the first speed to set the second distance to be the first distance.
