The photo drum is a very important component of copiers and laser printers.
It is with its help that toner is applied to a sheet of paper during printing.
Constructively, the photo drum is a metal cylinder (usually aluminum), covered with a layer of photoconductive material - a dielectric, the electrical resistance of which drops sharply under the influence of light radiation.
The photo drum is designed to first form a hidden electrostatic image of the document (exposure) on the photosensitive surface, and then to obtain a visible image (exposure) formed by toner particles and then transfer this image to the paper.
As a result, the same image that shines on the photo drum appears on the paper.
The photo drum is characterized by high reliability, long service life, and ease of maintenance.
