Development

The latent image constituted on the drum is developed into a visible image. The developing
roller contains a magnet core and an aluminum cylinder rotating around the magnet core
at a speed twice faster than that of the drum. Toner attracts to the developing roller since
it is magnetic. A magnetized blade above the developing roller constitutes a smooth layer
of toner in accordance with the roller revolution.
