Meaning
A photocopy is a duplicate document produced by a photocopying machine. It is an exact replica of the original document, including text, images, and formatting.
Origin
The concept of photocopying has been around for centuries, with early methods involving the use of tracing paper or sunlight. However, the first modern photocopying machine was invented in 1938 by Chester Carlson, an American physicist. Carlson's machine used a process called "xerography," which means "dry writing."
Xerography involves transferring a static electrical charge to a light-sensitive surface and then exposing it to light. The light creates a latent image, which is then developed with a powder toner that adheres to the charged areas. The toner is then transferred to paper, creating a photocopy.
Carlson's invention revolutionized the office environment and made photocopying a widespread practice. Today, photocopying machines are found in homes, offices, schools, and libraries around the world.
