(2) Electrification
A negative DC power is applied to the electrification roller to evenly negatively electrify
the surface of the OPC drum.
(3) Exposure
The LED head irradiates light on the surface of the OPC drum that is charged with a
negative electrical load. The negative electrical load attenuates according to the intensity
of light, for the irradiation area of the OPC drum surface. Further, the electrostatic latent
image is created on the OPC drum surface according to the electrical potential.
