Xerography is a dry photocopying technique. Originally called electrophotography, it was renamed xerography—from the Greek roots ξηρός xeros, "dry" and -γραφία -graphia, "writing"—to emphasize that unlike reproduction techniques then in use such as cyanotype, the process of xerography used no liquid chemicals.

When was xerography invented?

The xerographic process, which was invented by Chester Carlson in 1938 and developed and commercialized by the Xerox Corporation, is widely used to produce high-quality text and graphic images on paper. Carlson originally called the process electrophotography.

Who invented photocopy?

But 75 years ago, the technology that underpins the modern photocopier was used for the first time in a small apartment in Queens. Inventor Chester Carlson used static electricity created with a handkerchief, light and dry powder to make the first copy on Oct. 22, 1938.

Who invented electrostatic printing?

Carlson's innovation combined electrostatic printing with photography, unlike the dry electrostatic printing process invented by Georg Christoph Lichtenberg in 1778.

Why was xerography invented?

In 1938, Chester Carlson invented xerography out of two natural phenomena already known: materials of opposite electrical charges are attracted, and certain materials become better conductors of electricity when exposed to light.

Why is xerography used?

Xerography, also known as electrophotography, is a printing and photocopying technique that works on the basis of electrostatic charges. The xerography process is the dominant method of reproducing images and printing computer data and is used in photocopiers, laser printer s and fax machines.

What is the principle of xerography?

Electrophotography, more commonly known as xerography, is based on the formation of a latent electrostatic image on an imaging surface by first uniformly electrostatically charging the surface of the imaging layer in the dark and then exposing this electrostatically charged surface to a light and shadow image.

Why Selenium is used in xerography?

Selenium is used because it is able to hold and conduct charges in the absence and presence of light. Once the photo-conductor is charged a document begins to pass over the rotating drum. In most printing devices a laser is used to illuminate the document which projects an image onto the drum.
