(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 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.
