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.
(4) Developing
Toner is attracted to the electrostatic latent image on the image drum surface, converting it into a visible
toner image. Developing takes place through the contact between the image drum and the developing
roller.
1 As the toner supply roller rotates while rubbing on the developing roller, a friction charge is generated
between the developing roller and the toner, allowing the toner to be attracted to the developing roller (the
developing roller surface is charged positive and the toner, negative).
