ABSTRACT:
A light scanning device includes a light source that emits a laser beam, a deflector that deflects the laser beam emitted from the light source, a motor that drives the deflector so as to scan the deflected laser beam, an optical system that converges the deflected laser beam on an object surface, a housing configured such that the motor and the optical system are fixed thereto, the housing including one of a through hole penetrating from an inside thereof to an outside thereof and a thin portion whose wall thickness is thinner than any other portion of the housing, and a heat radiating member including an exposed portion that is exposed outside the housing, the heat radiating member being configured such that heat generated inside the housing is radiated outside the housing from the motor via one of the through hole and the thin portion, and the exposed portion.
