A photocopier (also known as a copier or copy machine) is a machine that makes paper copies of documents and other visual images quickly and cheaply. Most current photocopiers use a technology called xerography, a dry process using heat. (Copiers can also use other technologies such as ink jet, but xerography is standard for office copying.)

Xerographic office photocopying was introduced by Xerox in 1959, and it gradually replaced copies made by Verifax, Photostat, carbon paper, mimeograph machines, and other duplicating machines. The prevalence of its use is one of the factors that prevented the development of the paperless office heralded early in the digital revolution^{[citation needed]}.

Photocopying is widely used in business, education, and government. There have been many predictions that photocopiers will eventually become obsolete as information workers continue to increase their digital document creation and distribution, and rely less on distributing actual pieces of paper.

This example is of a negatively charged drum and paper, and positively charged toner as is common in today's digital copiers. Some copiers, mostly older analog copiers, employ a positively charged drum and paper, and negatively charged toner.

James Andrew McAvoy ( /ˈmækəvɔɪ/ MAK-ə-voi; born (1979-04-21)21 April 1979) is a Scottish stage and screen actor. He made his acting debut as a teen in 1995's The Near Room and continued to make mostly television appearances until the early 2000s. His notable television work includes State of Play, Shameless, and Frank Herbert's Children of Dune. Besides screen acting, McAvoy has appeared on stage with Three Days of Rain in 2009, and in 2011 he did voice work for animated films including Gnomeo & Juliet and Arthur Christmas.

Starting in 2003, McAvoy began to build his film resume with Bollywood Queen. That film was followed with The Chronicles of Narnia: The Lion, the Witch and the Wardrobe (2005), a commercial hit. His performance in Kevin Macdonald's The Last King of Scotland achieved him not only critical praise, but several award nominations. 2007's critically acclaimed Atonement marked the breakthrough in McAvoy's career. It also earned him a Golden Globe Award nomination and his second BAFTA nomination. Another big point in the actor's career was starring in Wanted (2008). Since then, he is notable for playing Charles Xavier in the 2011 superhero film X-Men: First Class.
