    • A differential sensitivity calculation portion calculates the differential sensitivity D of a toner concentration sensor, using an output voltage V1 and V2 of the toner concentration sensor when a toner chamber is in a state of toner concentration T1 and T2 at the time of initial operation of a printer, or at some other time. A toner replenishment control portion takes as input a current output voltage Vs output from the toner concentration sensor, calculates the toner concentration in the toner chamber using the output voltage Vs and the differential sensitivity D calculated by the differential sensitivity calculation portion, and outputs a control signal to a toner replenishment motor so as to maintain the toner concentration in the toner chamber at an appropriate concentration.

    • There is provided a laser radar apparatus including laser beam generating means, photo detecting means, a mirror assembly, light deflecting means, and rotation driving means. The laser beam generating means emits a laser beam having an axis thereof. The photo detecting means detects a reflected laser beam that is reflected back by an object. The mirror assembly includes a through-hole that transmits the laser beam and a reflecting surface that reflects a reflected laser beam reflected back by the object toward the photo detecting means. The light deflecting means has a flat mirror surface and a concave-shaped mirror surface, and reflects the laser beam toward a measurement range and deflects the reflected laser beam from the object toward the mirror assembly. The rotation driving means rotates the light deflecting means so as to direct the laser beam toward the measurement range.
