The charge roller is composed of two layers, a conductive layer and a surface protective layer, both
having elasticity to secure good contact with the image drum. When the DC voltage applied by the power
supply exceeds the threshold value, charging begins. The applied voltage is proportional to the charge
potential, with offset of approximately 550V.
(3) Exposure
Light emitted by the LED head irradiates the image drum surface with a negative charge. The surface
potential of the irradiated portion of the image drum 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.
