Abstract
In a light deflector including a polygon mirror having a plurality of reflecting surfaces; and a motor configured to rotate the polygon mirror, each of the reflecting surfaces, which has leading and trailing edges with respect to a direction of rotation of the polygon mirror and a center between the two edges, is configured to curve with the center displaced with respect to a reference straight line passing through the two edges in a plane perpendicular to an axis of rotation of the polygon mirror, radially, to a first side under a non-operating state in which the motor is not in operation, and to a second side (opposite to the first side) under a first rotating state in which progress of deformation of each of the reflecting surfaces has converged after a lapse of a first period of time from a start of rotation of the motor.
