ABSTRACT:
A light deflector wherein a polygon mirror rotating at a predetermined speed is used to deflect a beam of light irradiated from a laser light source to scan a photosensitive member or an original image with the deflected beam of light is improved in that the polygon mirror can be fixed firmly to the rotary member without disturbing smooth rotation of the polygon mirror. A screw member on which a male thread is formed is fitted on an outer periphery of the rotary member, and the polygon mirror is pressed against and secured to an annular mirror flange provided on the rotary member by a mirror cap screwed on the screw member.
