The image forming device is disposed near a rear focal point of a projection lens and has a projection plane formed of plural optical elements arranged in a matrix manner. The light source irradiates with light the projection plane.

The controller sets an output rate per unit time of the optical elements disposed at an end portion of the projection plane to be lower than that of the other optical elements. The light is output from the optical elements disposed at the end portion of the projection plane towards the projection lens at the output rate per unit time thereof.
