Definition: Xerography is a dry photocopying technique used to make quick and inexpensive copies of documents and images. It involves electrostatically charging a photoconductive surface and using light to transfer an image onto a piece of paper.
Etymology & Origin: The term ‘xerography’ comes from the Greek words ‘xeros,’ meaning ‘dry,’ and ‘graphia,’ meaning ‘writing’ or ‘drawing.’ The word was coined in the 20th century by Chester Carlson, who invented the process in 1938.
Examples:
- The invention of xerography revolutionised the office environment, making document duplication fast and affordable.
- Modern photocopiers and laser printers are based on the principles of xerography.
- Chester Carlson’s development of xerography laid the groundwork for the creation of Xerox Corporation, a major player in the copier industry.
