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. Un dispositif de balayage lumineux doté d'une pluralité de sources lumineuses comprend une unité de commande de sources lumineuses permettant de former L (L= 2) ensembles de faisceaux lumineux alignés sur une direction de sous-balayage. On obtient chacun de ces ensembles de faisceau lumineux L en faisant en sorte que les M sources lumineuses ((N-1)=M=1) de N (=1) des N (N=2) attribués à chacun des ensembles lumineux émettent de la lumière en tant que M sources émettrices de lumière. Chacun des L ensembles de faisceaux lumineux forment un pixel et un total de L pixels alignés dans la direction de sous-balayage est formé.
