(4) Development
The negatively charged toner comes in contact with the OPC drum to fuse the
electrostatic latent image by electrostatic force, to create a significant image on the
surface of the OPC drum.
The sponge roller precipitates toner on the development roller. The toner is then
negatively electrified.
The development blade removes excess toner from the development roller, then
a thin toner layer is created on the development roller.
The toner is sucked into the electrostatic latent image where the OPC drum and
development roller comes in contact.
(5) Transfer
The transfer roller is made of a conductive sponge. Paper is pressed against the
OPC drum surface, then the paper and OPC drum surface is adhered.
Paper is pressed against the surface of the OPC drum, then conveyed by the transfer
roller from behind. The toner and positive electrical load (that is reverse with the
toner) is applied, then the toner image is transferred to the paper.
When the power source applies powerful positive power on the transfer roller, the
positive electrical load induced by the transfer roller is transferred to the paper
surface at the contact point between the transfer roller and paper. The negative
electrical load toner is then sucked from the OPC drum surface on to the paper
surface.
