ビーム走査装置。 a light beam generator; a reflection device that receives an incident light beam and moves the reflected light beam in a traveling manner; a first focusing device that focuses the light beam incident from the light beam generator; and the reflection device. second and third focusing devices constituting a relay system for the light beam incident from the reflector, and a fourth focusing device configured to focus the incident light beam in a direction perpendicular to the light beam scanning direction of the reflecting device; a fifth focusing device that focuses the incident light beam at an image height of K·θ (K is a constant) on the scanning plane with respect to the incident θ; The incident light beam passes through a fourth focusing device and a second focusing device, and is focused on a reflection point of the reflecting device in a direction perpendicular to the traveling direction of the light beam of the reflecting device, so that the light beam of the reflecting device is focused. A first focusing device is arranged so that the light beam is collimated and incident on the reflection point of the reflecting device in the scanning direction, and the fourth focusing device is arranged so that the light beam is focused at a position where the light beam is focused by the light beam of the second focusing device. A second focusing device, a fourth focusing device, and a third focusing device arranged in the same position as the focusing device and configured to receive the light beam reflected by the reflecting device as described above; A light beam scanning device characterized in that the light beam passes through a fifth focusing device and is focused on a scanning surface.
