An optical scanning device is provided with a light source that emits a light beam, a driver that controls output power and modulation of the light beam emitted by the light source, a controller that transmits, to the driver, power control data and modulation data respectively used for controlling the output power and modulation of the light beam. The optical scanning device is further provided with a single data bus that connects the driver and the controller. The power control data and the modulation data being transmitted through the single data bus at different timing.
