Abstract
A scanning optical system projects a light beam from a light source as a line spread function image in a principal scanning plane before the light beam is made incident onto a scanning deflector. A static deflector is disposed in a line spread function image position in order to guide a light beam from a light source to the scanning deflector. The static deflector has a slit mirror for reflecting a light beam from the light source or a mirror with a slit for permitting a light beam to be transmitted therethrough.
