4-4-2-4. Developer Unit
On the surface where OPC drum and developer roller (rotate in opposite direction) meet, the toner that has negative electric
characteristic moves to the exposed part (-50V) due to the electric potential difference, but it will not move to the unexposed
part (-800V).

Toner on the OPC drum is transferred to paper by transfer unit. In other words, the toner on the OPC drum surface is induct-
ed by the transfer roller electrified to approximately +1.3KV(600~2800V variable) to the paper.
At this point, the voltage (600~2800V variable) is determined by temperature and humidity.
The above process is called "transfer".
