What Is Electrophotographic Laser?

The printing technique used in laser and LED printers and most copy machines. It uses electrostatic charges, dry ink (toner) and light. ... Using a laser or LEDs, a negative of the image is beamed onto the drum, cancelling the charge and leaving a positively charged replica of the original image.

What is the basic principle behind electro photography?

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.

What is xerographic process?

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.
