A sheet transporting device including a first and a second transporting rollers having different starting/stopping characteristics and capable of retransporting a sheet after the sheet is temporarily held between the first and the second transporting rollers. The sheet transporting device detects an amount of loop in a sheet which is produced between the first and the second transporting rollers and controls timing by which the second transporting rollers are started so as to delay the start until after the first transporting rollers are started in accordance with the detected amount of the loop.
