OKIFAX 5700/5900
A3 - 30
The image drum surface is charged to about -750 V by the contact charge of the
charge roller.
When the light from the LED head irradiates the image drum surface, the light energy
generates positive and negative carriers in the CGL. The positive carriers are moved
to the CTL by an electrical field acting on the image drum. Likewise, the negative
carriers flow into the aluminum layer (ground).
The positive carriers moved to the CTL combine with the negative charges on the
image drum surface accumulated by the contact charge of the charge roller, lowering
the potential on the image drum surface. The resultant drop in the potential of the
irradiated portion of the image drum surface forms an electrostatic latent image on it.
The irradiated portion of the image drum surface is kept to about -100 V.
