Image Transfer/Separation Section

Image Transfer/Separation Section
In this section, the toner image formed on the drum surface in the developing
section is transferred onto the paper supplied from the paper feed section,
then the paper is separated from the drum.

Transfer

The toner on the drum surface is positively charged from the developing unit.
As the paper passes under the image on the drum, the transfer charger
negatively charges the back of the paper. This causes the toner on the drum
surface to transfer to the paper.

Separation

The drum surface areas to which no toner is attracted are positively charged.
The paper, which was negatively charged in the transfer section, adheres to
the drum. To separate the paper from the drum, the separation charger
removes the charge from the paper immediately after the toner image has
been transferred. An AC voltage, with a positive DC bias, is applied to the
separation charger.
