Abstract
A laser scanning device includes a light source, a deflection portion, an image forming lens, and a light source control portion. The light source emits a light beam. The deflection portion causes the light beam emitted from the light source to scan a scanned surface by deflecting the light beam at a predetermined deflection angle. The image forming lens condenses the deflected light beam on the scanned surface, and causes the light beam to be scanned on the scanned surface in a scanning direction at an equal speed. The light source control portion controls the light source to irradiate the light beam to at least one section area among a plurality of section areas sectioned from each other in the scanning direction on the scanned surface, at a plurality of irradiation timings determined based on a position of the at least one section area in the scanning direction.
