Overview [D]
Figure 3
This machine uses mono-component toner, which is composed of resin and ferrite. The toner mix-
ing bar [A] stirs and carries toner to the toner application roller [B]. The toner application roller sup-
plies toner to the development roller [C]. As the development roller turns past the toner metering
blade [D], only a thin coating of negatively charged toner particles stays adhered to the develop-
ment roller.
During printing, a bias voltage is applied to the toner application roller and another bias voltage is
applied to the development roller. The toner is transferred from the toner application roller to the
development roller by the potential difference between these two rollers.
The development roller applies toner to the exposed areas of the latent image as they turn past
the drum.
