2. Exposure
The light emitted from the LED head is radiated onto the charged surface of the OPC drum.
The charge of the radiated part of the OPC drum attenuates according to the intensity of the
light, forming an electrostatic latent image on the OPC drum surface.
3. Development
Toner adheres to the electrostatic latent image on the drum surface, thereby turning the
electrostatic latent image into a toner image.
1. The sponge roller allows the toner to stick to the development roller.
2. The electrostatic latent image on the OPC drum surface is turned into a visible image
by the toner.
