Light deflector, two-dimensional image display apparatus, optical scanner, and image forming apparatus

A light deflector comprising:

• a mirror unit having a light reflection plane;
• a movable frame to support the mirror unit;
• a support frame disposed to surround the movable frame;
• a pair of serpentine beams each disposed between the movable frame and the support frame on both sides of the movable frame to form a turning shape, each of the serpentine beams having one end attached to the support frame, and another end attached to the movable frame;
• and
• a vibration damper provided on a portion that moves due to deformation of the serpentine beams caused by application of voltage being transferred to the mirror unit through the movable frame, so as to reduce vibration for the mirror unit.
