OKIFAX 5700/5900
B - 7
The EP (image) drum surface is charged to about -800 V by the contact charge of
the charge roller.
When light from the LED head irradiates the EP (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 EP (image) drum. Like-
wise, the negative carriers flow into the aluminum layer (ground).
The positive carriers moved to the CTL combine with the negative charges on the
EP (image) drum surface accumulated by the contact charge of the charge roller,
lowering the potential on the EP (image) drum surface. The resultant drop in the
potential of the irradiated part of the EP (image) drum surface forms an electro-
static latent image on it. The irradiated part of the EP (image) drum surface is kept
at about -100 V.
