Patent ID: 8199180

Claim:
An optical scanner comprising: a light source that emits a plurality of laser beams; a deflecting section that includes reflecting surfaces on each of which the plurality of laser beams emitted from the light source are incident, and that moves the reflecting surfaces to deflect the laser beams that are incident on the reflecting surface; a first optical element that reflects the plurality of laser beams deflected at the reflecting surface of the deflecting section and converges the laser beams in a slow scanning direction, and that can adjust positions, in the slow scanning direction, of the laser beams that the first optical element reflects; a second optical element that converges, in the slow scanning direction, the laser beams reflected at the first optical element, and that can adjust scan line tilt of the laser beams that the second optical element reflects; and a reflecting member that is planar and is provided on an optical path between the first optical element and the second optical element, and reflects, toward the second optical element, the laser beams converged in the slow scanning direction by the first optical element, the reflecting member having an adjusting mechanism that can adjust an angle of incidence in the slow scanning direction of the laser beams that are incident on the second optical element, wherein the reflecting member is supported by a first contact portion and a second contact portion that contact one surface of the reflecting member, a third contact portion that contacts another surface of the reflecting member, and an urging member that urges the reflecting member toward the first contact portion, the second contact portion and the third contact portion, and the adjusting mechanism adjusts the angle of incidence in the slow scanning direction of the laser beams that are incident on the second optical element by causing the third contact portion to advance or withdraw with respect to the reflecting member thereby to rotate the reflecting member with a rotation center line which is a straight line that connects the first contact portion and the second contact portion.
