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.
