Photocopier Machine

A piece of paper is placed over the powder image and then given a positive charge. The negatively charged powder is attracted to the paper as it is separated from the photoconductor. Finally, heat fuses the powder image to the paper, producing a copy of the original image

The xerographic process, which was invented by Chester Carlson in 1938 and developed and commercialized by the Xerox Corporation, is widely used to produce high-quality text and graphic images on paper. Because Xerox marketed the first plain-paper copiers, photocopying machines made by other companies are sometimes referred to as "Xerox machines" by those who dont realize its a misuse of the companys trademark. In addition, the xerographic process is actually used to make both copies and prints.
