2-1-4 Developing section
The latent image constituted on the drum is developed into a visible image. The developing roller contains a 3-pole (S-N-
S) magnet roller and an aluminum cylinder rotating around the magnet roller. Toner attracts to the magnet sleeve since it is
powdery ink made of black resin bound to iron particles. Developing blade, magnetized by magnet, is positioned approxi-
mately 0.3 mm above the magnet sleeve to constitute a smooth layer of toner in accordance with the magnet sleeve revo-
lution.
The developing roller is applied with the AC-weighted, positive DC power source. Toner on the magnet sleeve is given a
positive charge. The positively charged toner is then attracted to the areas of the drum which was exposed to the laser
light. (The gap between the drum and the magnet sleeve is approximately 0.32 mm.) The non-exposed areas of the drum
repel the positively charged toner as these areas maintain the positive charge.
The developing roller is also AC-biased to ensure contrast in yielding by compensating the toner’s attraction and repelling
action during development.
