What is Xerography?
A dry photocopying technique based on the electrostatic attraction of charged toner particles to a photoconductor surface that has been selectively discharged by light. The toner image is then transferred to paper and fused with heat. The process uses selenium or organic photoconductors.

Xerography is the operating principle of photocopiers and laser printers used ubiquitously in offices. Laser printers produce high-resolution documents using the xerographic process. The technology is also used in certain industrial printing and direct imaging applications.
Laser printers and copiers produce small amounts of ozone from corona discharge, which can cause respiratory irritation in poorly ventilated areas. Fine toner particles can be an inhalation hazard. Proper ventilation is recommended for high-volume printing environments.
