摘要： An optical scanning device deflects, by a common optical deflecting part, a plurality of groups of light beams emitted from a plurality of light sources and directs, by a scanning and imaging optical system, the groups of deflected light beams to respective scan surfaces so as to optically scan the scan surfaces. Each of the groups of light beams deflected by the optical deflecting part passes through at least two scanning lenses while being directed to a corresponding one of the scan surfaces. A first scanning lens arranged nearest to the optical deflecting part among the scanning lenses transmits the groups of light beams directed to the respective scan surfaces and satisfies Pm>0≧Ps, where Pm is a power in a main scanning direction and Ps is a power in a sub-scanning direction. A second scanning lens arranged nearest to the corresponding scan surface among the scanning lenses possesses a positive power in the sub-scanning direction and transmits only the group of light beams directed to the corresponding scan surface.

摘要： In an optical scanning device, a resin lens having a power that is an inverse (negative) power of a scanning lens is implemented in an optical system placed before a deflector so that a change in beam pitch caused by environmental temperature change can be prevented even when a resin lens is used as the scanning lens. To realize optical scanning using this device, a bundle of rays emitted from a plurality of light sources is coupled into a desired state by a coupling lens, after which the bundle of rays is incident on a resin lens. The surface of incidence of this resin lens has a spherical surface configuration with a negative power, and the exit surface of this resin lens has a cylindrical surface configuration with a negative power only in the sub scanning direction. Then, the bundle of rays passes through a resin lens that has a negative power only in the sub scanning direction and then enters a glass toroidal lens. A light deflector deflects the bundle of rays from the toroidal lens and the deflected bundle of rays is incident on a third optical system that compensates for a field curvature in each of the main scanning direction and the sub scanning direction, and focuses the bundle of rays onto a surface to be scanned while securing a desired beam pitch in the sub scanning direction.

摘要： Synchronization detecting units detect synchronization signals by receiving the light beam deflected to one side of a light source on one side of an optical deflector and receiving the light beam deflected to an opposite side of an optical axis of a scanning optical system from the light source on the other side of the optical deflector. Photodetectors that detect the synchronization signals are arranged on the opposite side of an optical axis of a scanning optical system from the light sources and on a side closer to the scanning optical system that detects the synchronization signals by receiving the light beam deflected to the light source.
