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.
In 1949, Xerox Corporation introduced the first xerographic copier called the Model A. Defeating computer leader IBM, Xerox became so successful that, in North America, photocopying came to be popularly known as “xeroxing”.
The technique was originally called electrophotography. It was later 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, this process used no liquid chemicals.
After consulting a professor of classical language at Ohio State University, Haloid and Carlson changed the name of the process to ” xerography “, which was derived from Greek words that meant “dry writing”. Haloid called the new copier machines “Xerox Machines” and, in 1948, the word “Xerox” was trademarked.

When was the xerography invented?
October 22, 1938: “Invention of Xerography”
Who invented xerography?
The term derives from the Greek words xeros , meaning dry and graphos , meaning writing. Xerography was invented in the late 1930s by an American patent lawyer named Chester Carlson.
When was the word xerography first used?
It is the text of the first xerographic image ever fashioned. It was created in a makeshift laboratory in Queens, NY. by a patent attorney named Chester Carlson, who believed that the world was ready for an easier and less costly way to make copies.
Who invented the xerography and what year?
The term derives from the Greek words xeros , meaning dry and graphos , meaning writing. Xerography was invented in the late 1930s by an American patent lawyer named Chester Carlson.
What is the process of xerography?
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.
How does Xerox machine works or xerography?
Most modern photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image.
What principle is xerography based on?
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.
How does a copy machine works?
In a photocopier, the light-induced conductivity of the drum is exploited to create a latent image in the form of electrical charges on the surface of the drum. This image is made visible and transferred to paper using a special, charged toner.
What are the steps of xerography?
As a photographic process, xerography employs a re-usable plate consisting of a thin layer of a photo-conductive material on an electrically conductive base. The plate is sensitized by electrostatic charging immediately before use. After exposure, the image is developed by dusting the plate with a micronized powder.
What is the principle of xerography?
Definition of xerography 1 : a process for copying graphic matter by the action of light on an electrically charged photoconductive insulating surface in which the latent image is developed with a resinous powder (such as toner) 2 : xeroradiography.
What does xerography mean?
Xerography is now used in most photocopying machines and in laser and LED printers.
What is xerography printing?
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.
