Chapter 2 Operation Description
(3) Exposure
Light emitted by the LED head irradiates the image drum surface with a negative charge. The surface
potential of the irradiated portion drops, forming an electrostatic latent image associated with the image
signal.
The image drum is coated with an underlayer (UL), a carrier generation layer (CGL), and carrier transfer
layer (CTL) on aluminum base. The organic photo-conductor layer (OPC), comprising CTL and CGL, is
about 20 µm thick.
The image roller surface is charged to about 750 V by the contact charge of the charge roller.
