2.2.3.3 Development Process
Toner in the Developer Cartridge (toner cartridge) is sent into the toner sending
roller area by the toner agitation blade.
The toner sending roller transports the toner to the development roller side.
The toner which has been transported onto the development roller forms a uniform
thin layer on the development roller by the operation of the 1st toner blade.
Negative charge is applied to the 2nd toner blade to give negative charge to the
toner.
Negative charge is applied to the development roller to keep the toner staying
there.
Toner sticks to the area exposed to the laser beam on the OPC drum.
The toner left on the development roller without sticking to the OPC drum is
collected into the toner hopper by the operation of the bias seal located under the
development roller. To this bias seal, the same bias voltage as is applied to the
development roller is applied to prevent toner from dropping.
The development bias voltage is adjusted by feedback control so that the print
density is automatically adjusted in the range of seven steps. In addition, reverse
bias voltage against the development bias is applied to prevent toner from sticking
to the OPC drum before printing start, before preliminary turning of the drum and
during preliminary turning.
