Claim:
1. A light scanning apparatus comprising: a housing providing a space; a light source module, installed on the housing, which emits a light beam; a light deflector, installed on the housing and on which the light beam emitted by the light source module is incident, and which is driven to deflect the incident light beam; an image forming optical system, installed in the space provided by the housing, which forms an image of the light beam deflected by the light deflector on a surface to be scanned; at least one flow blocking partitioning wall arranged between the light source module and the light deflector in the space provided by the housing and traversing a vertical plane in which the light beam emitted by the light source module travels to be incident on the light deflector, the at least one flow blocking partitioning wall having an opening or a transparent member through which the light beam emitted by the light source module passes to be incident on the light deflector, so that the at least one flow blocking partitioning wall thereby restricts air flows occurred as the light deflector is driven; and a cover which covers the housing.
