  • Publication number: 20250019192
    Abstract: A sheet feeding apparatus includes a sheet support portion supporting a sheet or sheets, a sheet feeding unit for performing a sheet feeding operation, an air sheet-separation unit for performing an air blowing operation, and a control unit for performing sheet feeding control to perform the sheet feeding operation by using the sheet feeding unit, in a state where the air blowing operation is in a stopped state, after the air blowing operation is performed by the air sheet-separation unit and the air blowing operation is stopped. In the sheet feeding control, after performing the air blowing operation, the control unit performs the air blowing operation again when performing the sheet feeding operation by using the sheet feeding unit on sheets of a set number of sheets set in advance based on an attribute of the sheet supported on the sheet support portion.
