Abstract
A light scanning device includes a scanning unit and a power consumption unit. The scanning unit faces a scan surface and performs scanning by dividing one scan area into segments by having multiple light-emitting-element groups arranged in a predetermined scanning direction. Each light-emitting-element group writes an image onto the scan surface by causing multiple light-emitting elements arranged in the scanning direction to emit light in a time-division manner based on image information. The power consumption unit operates during a non-writing period occurring between scanning processes repeatedly executed in each light-emitting-element group, so as to cause consumption of electric power corresponding to electric power consumed for light emission in the light-emitting-element group.
