The drum section consists of the charger roller unit, drum and cleaning section. The drum is electrically
charged uniformly by means of a charger roller to form a latent image on the surface. The cleaning section
consists of the cleaning blade and the cleaning roller which remove residual toner from the drum surface after-
transfer. The cleaning lamp consists of LEDs and removes residual charge on the drum before maincharging.
