Xerography is known as electrostatic copying or dry photocopying, is a process for making copies of documents using an electrostatic charge. The original document is placed on a photoconductive surface, which is then exposed to light. This causes the surface to become electrically charged, and the charge is then transferred to a sheet of paper. The paper is then developed, typically using toner, and the copy is made.
Xerography, also known as electrophotography, is a printing process that uses photoconductivity to transfer an image onto paper. The process begins with a photoreceptor, which is usually a photoconductive drum or plate, being given a positive or negative electrical charge. When exposed to light, the charge is discharged, creating an electrostatic field. This field is then used to attract and hold toner particles, which are transferred to the paper to create the print.
Xerography is commonly used for office printing, as it is fast and efficient. It is also used for high-quality printing, as the process can produce prints with resolutions of up to 1200 dpi. Xerography has a number of advantages over other printing processes, including its speed, accuracy, and lack of need for pre-press operations.
Xerography was first developed in the early 1940s by American physicist Chester Carlson. He originally called his invention “electrophotography.” The first commercial xerographic copier was launched in 1959 by Xerox Corporation.
Xerography is used in a variety of printing applications, including photocopiers, laser printers, and multifunction printers. It is also used in some fax machines.
Xerography has been an important printing technology since its invention in the 1930s. This technology has allowed for the mass production of printed materials, including books, newspapers, and magazines. Xerography has also been used to print labels and packaging, as well as to create signage and other printed advertising. In recent years, Xerography has become increasingly popular for digital printing, as it offers a high-quality, cost-effective printing solution.
