    摘要： An optical scanning device includes an enclosure having a plurality of windows covered with transparent members. The enclosure houses a plurality of light sources, a scanning portion, optical elements and a light amount attenuation portion. The scanning portion deflects each of a plurality of light beams emitted from a plurality of light sources at a constant angular speed in a main scanning direction. The optical elements constitute respective light paths from the scanning portion to the windows for the plurality of light beams, respectively. The light amount attenuation portion attenuates light amount in a light path of a first light source among the plurality of light sources in a downstream side of the position where a light beam emitted from a second light source enters as stray light. The drive portion drives the first light source so as to compensate for light amount attenuated by the light amount attenuation portion.

    摘要： A laser scanning optical system converts a plurality of beams emitted from the laser diode (LD) into parallel light using a collimator lens, shapes the parallel light using an aperture, and executes exposure of a plurality of lines simultaneously on a photoreceptor drum. To cause a necessary emitting point interval d determined uniquely from the magnification of the optical system to coincide with an emitting point interval of the LD used, the LD is rotated by an angle θ against the main optical axis plane thereof. In this case, a converting device that converts the aspect ratio of a profile of the light beam emitted from the LD is provided. A conversion characteristic of the converting device is adjusted such that the characteristic is matched with a condition within a predetermined region following a characteristic of the optical system.
