Abstract:
Scanning optical unit includes: light source; incident optical system including one coupling lens for converting light from the light source into a light beam; optical deflector having a reflecting surface and configured to reflect and deflect the light beam in main scanning direction; and scanning optical system for focusing the deflected light beam on an image surface. The incident optical system converges the light beam on the reflecting surface in sub-scanning direction. Further, 0.01≤(βs/βm) 2 ≤0.27 and βs2<1 are satisfied, where βm is a lateral magnification of the entire optical system from the light source to the image surface in the main scanning direction, βs is a lateral magnification of the entire optical system in the sub-scanning direction, and βs2 is a lateral magnification of the scanning optical system from the reflecting surface of the optical deflector to the image surface in the sub-scanning direction.

Claim (Index 1):
A scanning optical unit comprising:\n a light source; an incident optical system including one coupling lens configured to convert light emitted from the light source into a light beam; an optical deflector having a reflecting surface and configured to reflect and deflect the light beam from the incident optical system in a main scanning direction; and a scanning optical system configured to focus the light beam deflected by the optical deflector on an image surface, wherein the incident optical system is configured to converge the light beam on the reflecting surface of the optical deflector in a sub-scanning direction orthogonal to the main scanning direction, and wherein the following conditions are satisfied:\n 0.01\u2264(\u03b2 s/\u03b2m ) 2 \u22640.27 and \n \u03b2 s 2<1 \n where \u03b2m is a lateral magnification of an entire optical system from the light source to the image surface in the main scanning direction, \u03b2s is a lateral magnification of the entire optical system in the sub-scanning direction, and \u03b2s2 is a lateral magnification of the scanning optical system from the reflecting surface of the optical deflector to the image surface in the sub-scanning direction.
