Abstract

A scanning optical device includes: a first semiconductor laser; a second semiconductor laser; a first coupling lens configured to convert light from the first semiconductor laser into a first light beam; a second coupling lens configured to convert light from the second semiconductor laser into a second light beam; a deflector configured to deflect the first light beam and the second light beam; a first optical sensor configured to detect the deflected first light beam; a second optical sensor configured to detect the deflected second light beam; a first scanning optical system configured to form an image using the deflected first light beam; a second scanning optical system configured to form an image using the deflected second light beam; and a circuit board. The first semiconductor laser, the second semiconductor laser, the first optical sensor, and the second optical sensor are mounted on the circuit board.
