  • Sheet-transporting device and image-forming apparatus
    Patent number: 6340156
    Abstract: A structure including a transporting roller for transporting sheets; and a curling roller for transporting the sheets at a location downstream from the transporting roller in a sheet-transporting direction, the driving torque of the curling roller being larger than the driving torque of the transporting roller. The transporting roller and the curling roller are constructed so that their speeds can be switched from a first transporting speed to a second transporting speed which is greater than the first transporting speed. The time required to switch the speed of the curling roller from the first transporting speed to the second transporting speed is made longer than the time required to switch the speed of the transporting roller from the first transporting speed to the second transporting speed.
