Abstract
A laser scanning device includes a device body, and a rotating polygonal mirror rotatably mounted in the device body and deflecting light projected from a light source. A cover member is mounted in the device body to cover the rotating polygonal mirror. The cover member has a slit for transmitting the light and an influent hole for letting external air flow in, and forms an air current rotating and descending at high speed around the rotating polygonal mirror. A dust collection member filters off dust included in the air flowing into the cover member through the influent hole by the air current generated in the cover member.
