ABSTRACT:
A vibration mirror used in an optical scanning device has two reflection surfaces on opposite sides. A pair of light beams corresponding to a pair of different colors are irradiated on one reflection surface and another pair of light beams corresponding to another pair of different colors are irradiated on other reflection surface. If there are fluctuations in dimensions or a change in temperature, because the vibration mirror is one, all the colors are subjected to the same influences.
