Optical scanning device and image-forming apparatus |
摘要 |
In an optical scanning device for forming an electrostatic latent image on an image-bearing body with scanning beam released from a light source, a support body having a plurality of supporting faces and first and second optical means for directing the scanning beam from the light source onto the image-bearing body are installed. Moreover, in the support body, a light transmitting means for transmitting the scanning beam from the first optical means to the second optical means is installed in the vicinity of a ridge portion thereof that is the least susceptible to deformation and distortion and strongest in its strength. Thus, it becomes possible to improve a light image in its precision that is formed by the scanning beam directed onto the image-bearing body.
