A sheet conveying apparatus includes a sheet feed tray on which sheets of a plurality of sizes which differ in length in a sheet widthwise direction perpendicular to a sheet conveying direction, a conveying unit which conveys a sheet on the sheet feed tray to a predetermined processing position, a sheet position detector which has a plurality of light-emitting units respectively arranged at positions corresponding to different sheet widths and one light-receiving unit capable of moving to positions corresponding to the plurality of light-emitting units, a light reception position detector which detects the position of the light-receiving unit, and a control unit which selects one of the plurality of light-emitting units on the basis of a detection result from the light reception position detector. The sheet position detector causes the selected light-emitting unit to emit light and detects the convey position of an end portion of a sheet in the widthwise direction which is conveyed by the conveying unit on the basis of an output signal from the light-receiving unit when the light-emitting unit is caused to emit light.
