Fotokópiázás

Fotokópiázás, also known as photocopying or xerography, is a dry copying process in which light causes an electrically charged coating on a piece of paper to become conductive. The paper is then treated with a powdered ink, or toner, which adheres to the charged areas, creating an image. This toner is then fused to the paper by heat or pressure, resulting in a permanent copy.

The invention of the photocopier is credited to Chester Carlson, who developed the process in the late 1930s and early 1940s. He founded the Haloid Company, which later became Xerox Corporation, and the first commercial photocopier, the Xerox 914, was introduced in 1959. The technology revolutionized document reproduction, making it faster, more accessible, and more affordable than previous methods like carbon paper or mimeographs.

Photocopying is widely used in offices, schools, libraries, and homes for duplicating documents, reports, articles, and other printed materials. Modern photocopiers often incorporate features like color copying, scanning, and printing, integrating multiple office functions into a single device. Despite the rise of digital document management and printing technologies, photocopying remains a common and practical method for creating physical copies of existing paper documents. The process is generally straightforward, requiring users to place the original document on the copier's glass or feed it through a document handler, select the number of copies, and initiate the copying cycle.
