The photo drum is an 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 form an initially hidden electrostatic image of a document on a photosensitive surface (exposure), and then - obtaining an image of the visible (manifestation) formed by toner particles and, then, transferring this image to paper.
As a result, the same image that shines on the photo drum is produced on paper.
The photo drum is characterized by high reliability, long service life, and ease of maintenance.
