Abstract
A sheet conveying apparatus includes a curved sheet conveyance path through which a sheet passes, and a sensor that is disposed in the sheet conveyance path and detects the passing sheet. The sensor includes a light-emitting portion that collects light from a light source and irradiates the passing sheet in an irradiating range which is broader in a sheet conveyance direction than a width direction, and a light-receiving portion that receives the light arriving at and reflected from the sheet.
