摘要： A laser beam printer is provided which is capable of compensating for the difference in diameter between dots every colors and preventing unintentional coloring of the boundary between colors. In a conventional light source used for a printer, a spot diameter thereof is small upon low output and large upon high output. However, in a semiconductor laser device of the present invention, which is used for a light source for a printer, the spot diameter of the light source is controlled so as to be large upon low output and small upon high output. It is thus possible to keep the spot diameter of the laser light source constant. As a result, an irregular color-free laser beam printer can be materialized.
