Summary:PROBLEM TO BE SOLVED: To provide a sheet feeder with high quality by accomplishing reduction of load torque of a conveying motor and prevention of wrinkle of sheet. SOLUTION: A suction duct 8 is arranged such that a suction opening part 8a is positioned at an inner side of a suction conveying belt 6, and the sheet S is sucked to the suction conveying belt 6 by making the inside pressure of the suction duct 8 negative by a suction fan 14. A shutter 16 is arranged between the suction opening part 8a and the suction fan 14 to perform communication and shutting off of the suction opening part 8a and the suction fan 14. Further, an opening/closing member 20 capable of opening/closing the opening part 18 for communicating the inside with the outside of the suction duct 8 is provided and the negative pressure in the suction duct 8 is released by opening the opening part 18 by the opening/closing member 20 in response to shutting off action of the shutter 16.
