1. A photocopying machine designed for electrostatic printing.
2. A printing copier which employs principles of electrostatography or all of the processes involving the forming and uses of electrostatic charged patterns for recording and reproducing images.
3. A type of copier that employs the principles of photoconductivity and electrostatic attraction.
4. A copying machine in which a photosensitive material is electrically charged in the pattern of the original being copied, and the potential image is developed by applying a finely powdered carbon toner which has been oppositely charged.

Examples include Xerox and Electrofax copying processes.

1. A process in which an electrostatically charged printing plate is exposed so that the resulting positive image attracts a negatively charged resin.
2. The process of recording and reproducing visible patterns with the formation and utilization of inactive electrostatic charge patterns.
3. A generic term covering all processes involving the forming and use of electrostatic charged patterns for recording and reproducing images.

This field of recording and reproducing images is divided into electrophotography and electrography.
