The sheet conveying apparatus includes a conveying belt including a placement area having a suction hole, and configured to convey a sheet with a vacuum force from the suction hole, a sheet supply unit capable of supplying a sheet to a supply position of the sheet with respect to the conveying belt; and a control unit configured to control the conveying belt so as to further move the conveying belt after the conveying belt conveys a last sheet to be conveyed. The control unit causes the conveying belt to wait after moving the placement area to a predetermined position in an area from a position in an upstream direction with respect to the moving direction of the conveying belt to the supply position in a conveying amount of the conveying belt corresponding to a time required for the sheet supply unit to convey a next first sheet to the supply position.
