With the drum being sensitive, appropriate areas of the drum are actually sensitized or desensitized according to the amount of reflected light of the image received. Toner is then attracted to the drum, from the electrical charge produced by the Primary Charge Corona wires and from the intensity of light received. The toner image on the drum will then be next transferred onto the paper. The Drum is a consumable part. A modular unit which houses the developer and toner.
Developer is either finely milled iron filings or magnetic ferrite.
Developer and Toner are consumable supplies. A modular unit which mechanically removes the latent image from the previous copy made away from the drum. The Cleaning blade is nothing more than a silicone rubber strip attached to a metal bracket. This blade comes in direct contact with the Drum and physically removes the latent image from the previous copy made. The Cleaning Blade is a consumable part.
