Electrostatic imaging printing principle is first will photosensitive drum in the dark charging, make its uniform zone in charge, and then through the laser scanning way will be required to produce image projection to rotate the photosensitive drum surface on the photoconductor, light conductor is lighting part resistance decreased, but the charge through the light conductor loss, but not light part retained the charge. In this way, the photosensitive drum surface on the left with the original image of the same charged image, which is known as "the electrostatic latent image", will with electrostatic latent image the photosensitive drum contact charged ink or toner (the symbol and electrostatic latent image opposite), through the charged toner and electrostatic latent image between the coulomb force to realize the visualization of latent image (development), namely the photosensitive drum has been exposed part of the adsorption toner, form the image, then toner image transferred to the printing on things.
Electrostatic imaging printing (electrostaticprinting) refers to the use of the image carrier with static or coated with special coating printing content, the use of such as electrostatic photographing, ion deposition or magnetic imaging printing process form latent image, through the toner materials make latent image converted into a visible image.
The last thing to transfer to printing the toner heating, upper fuser, make the toner resin melting, firmly bonding on paper, you can get a printed with the original image, is completed electrostatic printing process (Gold Printing Group)
