A light scanning device includes: a movable section which has a light reflection section reflecting light and oscillates around an oscillating axis and in which a maximum deflection angle thereof is variable; and a detection section which detects the maximum deflection angle of the movable section, wherein the detection section includes a light source which irradiates light toward the light reflection section, a light-receiving section which receives reflected light of the light from the light source, reflected by the light reflection section, and a displacement drive section which changes a position of the light-receiving section in accordance with the maximum deflection angle of the movable section. |
