Abstract
A light scanning apparatus having plural light sources includes a light source control unit configured to control the light sources to form L (L≧2) light beam arrays aligned in a sub scanning direction each of which L light beam arrays are formed by causing M ((N−1)≧M≧1) light sources out of N (N≧2) light sources assigned to each of the L light beam arrays to emit light as M light emitting sources, wherein each of the L light beam arrays forms a pixel and a total of L pixels aligned in the sub scanning direction are formed.
