And How It Uses Electrostatics
How does it work with electrostatics?
2. Exposure: The original document is illuminated by a lamp, and the white areas of the document reflect the light onto the drum. The drum becomes conductive on the spots where the light shines and discharges to the the ground. The area of the drum that is not exposed to the light from the lamp is still negatively charged.
3. Developing: The toner is positively charged, and when put on the drum to develop the image, it is attracted to and sticks onto the negative areas on the drum.
4. Transfer: The image on the surface of the drum is moved onto a piece of paper with a higher negative charge than the drum.
5. Fusing: The toner is melted and stuck to the paper by heat and pressure rollers.
