| XEROGRAPHY Xerography (which means "dry writing" in Greek) is a proces of making copies that was invented in 1938 by Chester Floyd Carlson (1906-1968). Xerography makes copies without using ink (hence its name). In this process, static electricity charges a lighted plate; a plastic powder (called toner) is applied to the areas of the page to remain white. Carlson marketed his revolutionary device to about 20 companies before he could interest any. The Haloid Company (later called the Xerox Corporation) marketed it, and photocopying eventually became common and inexpensive. |
