1. An optical deflecting device comprising:

  • a plate-like member having a light reflective area and a conductor layer, the plate-like member rotating with substantially the middle portion thereof made a fulcrum to change an inclination direction thereof and thereby a reflection direction of a light flux incident to the light reflective area being changed; and

    a first electrode group and a second electrode group arranged so as to oppose the conductor layer of the plate-like member, respectively, and to sandwich a position corresponding to a position of the fulcrum of the plate-like member, each electrode group including a control electrode controlling starting of the plate-like member and a drive electrode driving the plate-like member.
