摘要:
A sheet feeding apparatus includes a sheet feeding unit configured to suction a stored sheet with a negative pressure to feed the suctioned sheet, a suction duct connected to the sheet feeding unit, a suction fan configured to generate a negative pressure in the suction duct, a shutter disposed in the suction duct and configured to allow and shut off communication between the sheet feeding unit and the suction fan, and a communicating mechanism configured to cause a space in the suction duct between the shutter and the sheet feeding unit to communicate with an outside of the suction duct. The communicating mechanism is configured to cause the space in the suction duct to communicate with the outside of the suction duct according to the shutter shutting off communication between the sheet feeding unit and the suction fan.
