Abstract

PURPOSE: To prevent electrostatic disturbance occurring on the reference plane of the polyhedral mirror of light deflecting device and float member, by making the reference plane of polyhedral mirror and float member from conductive material, and grouding them.
CONSTITUTION: A float member 7 is made from conductive resin, and is grounded by means of an earth wire 11. A polyhedral mirror 6 is made from a metal material, and a reference plane 6-2 is ground sufficiently. The reference plane 6-2 of the polyhedral mirror and float member 7 may be coated with conductive materials. A large quantity of static electricity occurs on the surface of reference plane 6-2 and float member 7 due to friction caused by sliding contact, thereby attracting fine dust, which causes to disturb the float due to fluid pressure of the reference plane of the polyhedral mirror. In this constitution, therefore, electrostatic disturbance of the light deflecting device may be prevented, so that the performance of the light deflecting device may be maintained stably.
