The image roller 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.
