    2.5.2 Exposure Stage After the drum is positively charged, it is exposed to the light emitted from the laser unit. Laser Beam Drum Paper Laser beam f  lens Laser detector Polygon mirror Laser diode Motor Lens Fig. 2.28 The area exposed to the laser beam is the image to be printed. The surface potential of the exposed area is reduced forming the electrostatic image to be printed.
  • Page 39: Developing

    2.5.3 Developing Developing causes the toner to be attracted to the electrostatic image on the drum so as to transform it into a visible image. The developer consists of a non-magnetic toner. The development roller is made of conductive rubber and the supply roller which is also made of conductive sponge rotate against each other.
  • Page 40: 2.5.5 Drum Cleaning Stage

    2.5.5 Drum Cleaning Stage In the image transfer stage, not all the toner on the photosensitive drum is transferred onto the paper but some remains on the drum. In the drum cleaning stage, the drum surface is cleaned by the cleaning roller, so that residual toner on the drum surface is removed and collected on the cleaning roller itself.
