Abstract
In a light scanning method of scanning a light beam emitted from a light source on a plane to be scanned, a focal distance of an optical element that converges light emitted from the light source onto the plane to be scanned is sequentially varied to uniform a beam spot diameter at each position on the plane to be scanned where a distance from the light source varies.
