ABSTRACT:
A light scanning apparatus is provided that has plural light sources which scan plural light beams in a main scanning direction. The light scanning apparatus comprises a light source control unit that controls the plural light sources. Where an array of N (N≧2) light sources aligned in a sub scanning direction and capable of scanning different positions in the sub scanning direction is called a virtual light source array, and where L (L≧2) virtual light source arrays aligned in the sub scanning direction are formed, the light source control unit causes M ((N−1)≧M≧1) light sources out of the N light sources of each of the L virtual light source arrays to emit light to form a pixel and thereby to form a total of L pixels aligned in the sub scanning direction by giving the same data to the M light sources of each of the L virtual light source arrays.
