A photocopier is an electronic device that is designed to reproduce pages and images instantly and cost effectively. The main features of a photocopying machine include the ability to enlarge and minimize images, reproduce the color images, stapling, fastening, creating overhead transparencies, and collating or arranging the pages of a book in correct manner for binding. A photocopier works based on the attractive force between the objects with different electric charges where some objects become better electrical conductors when illuminated by light.
