摘要： An optical deflector includes a driving mirror, which is driven to rotate and has a deflecting surface for deflecting an incident light. Gratings are formed on the deflecting surface, each grating having a shape that makes the intensities of light beams diffracted at a positive order and a negative order different from each other. A main scanning line formed by a trace of the deflected light according to the rotation of the driving mirror is a straight line. The optical deflector is used in an optical scanning apparatus with a light source. The optical scanning apparatus is utilized in an image forming apparatus for forming an electrostatic latent image onto an exposure object.
