Abstract
A disclosed optical scanning device includes a light source unit configured to emit a laser beam; an oscillating mirror configured to deflect the laser beam from the light source unit; a scanning/imaging optical system configured to focus the deflected laser beam on a target surface; and plural light-receiving elements configured to receive the laser beam in a scanning area of the laser beam, the position of the oscillating mirror being adjusted such that time intervals between output pulses in output signals of the respective light-receiving elements become substantially the same between the light-receiving elements and/or widths of the output pulses become substantially the same between the light-receiving elements.
