%Charging(2) Charging
Charging is actuated by the application of the DC voltage to the charge roller that is in contact with the
image drum surface.
The charge roller consists 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 an offset of approximately 550V.
