Techopedia Explains Xerography

The word xerography originated from two Greek words: xeros (meaning dry) and graphos (meaning writing/drawing). The process of xerography relies on photoconductive properties of substances which show a decrease in electrical resistance when exposed to light, hence naturally grayscale images are better quality-wise. In fact, xerography was originally only for printing or reproducing grayscale images. It was later developed to print colored images as well. The technique has been rapidly gaining popularity since its introduction in the 1940s.
