Abstract
An optical scanning device and an imaging apparatus are provided. The optical scanning device includes a light source for emitting a light beam, a first optical unit for collimating the light beam emitted by the light source in a main scanning direction and focus the light beam in an auxiliary scanning direction, an optical deflector for deflecting the light beam, and an imaging optical system for guiding the light beam to a scanned surface for imaging. When the optical deflector deflects the light beam at a maximum deflection angle, the light beam in the main scanning direction forms a maximum incident angle Φwith a normal line of the scanned surface. A spot tilt rate e/a of a light spot on the scanned surface satisfies where a is a size of the light spot in the main scanning direction and e is a spot tilt.
