A dry copying process in which black or colored powder adheres to parts of a surface remaining electrically charged after being exposed to light from an image of the document to be copied.
- ‘Most current photocopiers use a technology called xerography, a dry process using heat.’
- ‘In 1937, the process called Xerography was invented by American law student Chester Carlson.’
- ‘‘The more you understand about xerography,’ pioneering Xerox engineer Bob Gundlach tells Owen, ‘the more you are amazed that it works.’’
- ‘The process, later renamed xerography (dry writing), used electrostatic energy to transfer dry ink to a page.’
- ‘Had he not conceived of xerography, the plain paper copier might have remained un-invented for decades.’
