1.2.4 DEVELOPMENT
Overview
This machine uses mono-component toner, which is composed of resin and ferrite.
The toner mixing bar [A] stirs and carries toner to the toner application roller [B].
The toner application roller supplies 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 development 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.
