A sheet feeding device, capable of reliably feeding sheets that have a curl, includes a sheet surface detection mechanism configured to detect an upper surface of a topmost sheet of sheets supported on a tray. The sheet surface detection mechanism includes a sensor unit arranged on a upstream side of a suction and conveyance mechanism in a sheet conveyance direction, a sensor lever configured to turn the sensor unit ON/OFF, and a detection unit having one end connected to the sensor lever and another end that extends toward a downstream side in the sheet conveyance direction. The detection unit includes, on a downstream side in the sheet conveyance direction, a protruding member that protrudes in a downward direction and that is capable of contacting the topmost sheet supported on the tray.
