Xerography | Definition, Etymology, Synonyms & Antonyms

Xerography (noun)

Definition

Xerography is a photocopying or electrostatic printing process that uses electrostatic charges to reproduce images and text on paper. It involves creating an electrostatic image of the original document or image on a charged surface and then transferring toner (powdered ink) to the paper to create a copy.

Etymology

The term xerography is derived from two Greek words: “xeros,” meaning “dry,” and “graphia,” meaning writing or drawing. The name reflects the dry nature of the process, as it does not involve the use of liquid ink.

Synonyms

Photocopying
Electrostatic printing
Copying
Reproduction
Duplication

Antonyms

Handwriting
Original creation
Freehand drawing

Example

In the 20th century, xerography revolutionized the way documents were duplicated and shared. The invention of the photocopier allowed businesses and individuals to easily reproduce important papers, saving time and resources.

FAQs (Frequently Asked Questions)

Who invented xerography?

Xerography was invented by Chester Carlson, an American physicist and inventor, in the 1930s. He developed the concept and received a patent for it in 1942. The first commercial photocopier, the Xerox 914, was introduced by the Xerox Corporation in 1959.

How does xerography work?

Xerography involves several steps:

Charging a photoconductive drum or surface with static electricity.
Exposing the charged surface to light creates an electrostatic image of the original document.
Applying toner (powdered ink) to the charged surface. The toner adheres to the areas with the electrostatic charge.
Transferring the toner image onto paper and fusing it using heat, creating a permanent copy.

What are the advantages of xerography?

It offers quick and efficient document reproduction. This term produces high-quality copies, allows for easy adjustments in size and contrast, and requires minimal setup time. It also enables the creation of multiple copies without the need for re-inking.

Is xerography still used today?

While digital technology and laser printing have become more prominent in recent years, xerography is still used for certain applications. Many office photocopiers and some commercial printing applications still utilize xerography principles.

What is the difference between xerography and laser printing?

Xerography and laser printing are similar processes that both involve creating an electrostatic image on a photoconductive surface. The main difference is in how the image is created and transferred to paper. The entire image is formed on the photoconductive drum before being transferred.
