Abstract:
1. An optical scanning device comprising: a beam generating unit configured to generate a beam of light; a scanning unit with a plurality of scanning planes configured to deflect the beam of light generated by the beam generating unit and cause the beam of light to scan an image carrier in a main-scanning direction; a micro mirror configured to deflect the beam of light generated by the beam generating unit and thereby enable the deflected beam of light to fall on the scanning unit; a position detecting unit configured to detect a position of the beam of light deflected by the micro mirror; an input voltage control unit configured to control an input voltage value for inclining the micro mirror and thereby causing the beam of light to deflect; and an input voltage determining unit configured to control the input voltage value controlled by the input voltage control unit according to a detection result obtained by the position detecting unit.
