6.2.2 Development Mechanism
The development unit contains four development mechanisms in one body,
one for each color. Each development section is reduced in size with respect
to previous models, and can hold 400 g (1 package) of developer.
The developer from the dual mixing roller [A] is attracted to the surface of the
development roller [B] by the magnets inside the development roller. The
attracted developer is trimmed to the desired thickness by the doctor blade
[C], and it is then carried to the drum [D] where the latent image is developed.
Each color has a hopper [E]. The hopper is divided into a main hopper [F], a
sub hopper [G], and a toner supply section [H].
