Optical scanning device moving gravity center of pixel in sub-scanning direction, image forming apparatus having light sources, and method |
摘要 |
An optical scanning device includes n-odd (n≧2) light sources disposed at different positions at least in a sub-scanning direction, a pixel forming part in which one pixel is depicted by light beams emitted from m-odd (n≧m≧2) light sources of the n-odd light sources and a distance of adjacent light sources for emitting the light beams in the sub-scanning direction is less than 5 μm, and a light source driving control part configured to control an emitting state of the light sources for depicting the one pixel and conduct an emission driving control for moving a gravity center of the one pixel in the sub-scanning direction. |
