3.4.3 Development
When the toner has been moved through under friction between the Developing
Roller (DR) and Supply Roller (SR), the surface of the Developing Roller will be
covered with a layer of charged toner. After exposure, as the OPC goes through
the DR, it will transmit the developing voltage to the DR. This voltage is greater
than that of the exposed portion of the OPC and less than that of the unexposed
portion. Toner will be attracted to the exposed area of the OPC due to the
electrostatic field between the OPC and DR, and a visible image will form.
3.4.4 Print Transfer
When the paper moves through the interlayer between the Transfer Roller (TR) and
the photosensitive drum (OPC), the TR will gain high pressure opposite to the toner
charge polarity. The toner will therefore be affected by the TR's electrical field,
transferring toner to the surface of the paper. After moving through the TR, the
back of the paper is positively charged. This causes the toner, separated by the OPC,
to be attracted to the paper until the next stage. There is also an anti-static needle
to discharge extra charge that may be produced throughout the process by the
electric field and the friction of the paper and the toner.
