MX-M316N OPERATIONAL DESCRIPTIONS 11 – 22
B. Developing operations
Electrostatic latent images formed on the OPC drum surface by the
laser (writing) unit (laser image beams) are converted into visible
images by toner.
Toner in the developing unit is stirred by the mixing roller.
When toner is stirred, it is negatively charged by mechanical friction.
The developing bias voltage (negative) is applied to the developing
roller.
Negatively charged toner is attracted and attached to the area on the
OPC drum where negative voltage is reduced by exposure.
On the other hand, the negative voltage at an area where exposure is
not made is higher than the developing bias voltage, and toner is not
attached.
