An optical scanning device includes a light source component, a scanning component, an electrostatic driver, a controller, and a current sensor. The light source component emits light. The scanning component scans the light. The driver drives the scanning component. The controller controls emission of the light from the light source component. The current sensor senses current generated by a capacity change of the driver. The controller further controls the emission of the light from the light source component based on the sensed current sensed by the current sensor.
