A light-receiving element that receives the reflected light, and a low light reflectance element that occupies a position inside the advancing original paper in the merging path and absorbs the light from the light-emitting element when there is no photosensitive paper to merge with the original paper. A photosensitive paper detection device comprising a light absorbing member.
