The photodetector receives a light flux that travels on the other optical path. The control section controls an emitted light quantity in the laser light source, based on a quantity of the light flux received by the photodetector. The light-quantity-distribution control device is disposed between the optical-path branching device and the photodetector on the other optical path. The light-quantity-distribution control device controls a light quantity distribution in the light flux to be incident upon the photodetector.
