Abstract: An optical scanning apparatus includes an optical deflector that deflects a light beam at a substantially constant angular velocity and an optical system that condenses the deflected light beam onto a to-be-scanned surface thereby performing optical scanning of the to-be-scanned surface. The to-be-scanned surface is a surface of a latent image carrier having a charge generation layer that generates carriers and a charge transport layer. A driving unit drives the optical deflector at a scanning frequency at which exposure is attained in a state where the carriers generated at the charge generation layer of the latent image carrier substantially stay still.

Abstract: An optical scanning device includes a plurality of optical scanning, units each including a light source emitting a light flux, a scanning input optical system directing the light flux emitted from the light source to a deflector. The deflector deflects the light flux so as to cause the light flux to scan a surface to be scanned. A scanning and imaging optical system condenses the light flux deflected by the deflector so as to form a beam spot thereof on the surface to be scanned. The optical scanning device scans the surface to be scanned continuously through coordinated movements of the plurality of optical scanning units, and the respective scanning and imaging optical systems of adjacent at least two of the plurality of optical scanning units have one lens in common.
