1 | Developing roller |
|
| Attaches toner to the latent electrostatic |
|
|
|
|
| images on the OPC drum to convert it into |
|
|
|
|
| a visible image. |
|
|
|
|
|
|
|
2 | Developing doctor |
|
| Controls toner quantity on the developing |
|
|
|
|
| roller and charges toner. |
|
|
|
|
|
|
|
3 | Developing bias |
|
| Connects the developing roller and the bias |
|
| electrode |
|
| voltage output (high voltage PWB). |
|
|
|
|
|
|
|
4 | Potential control |
|
| Connects the developing roller and the bias |
|
| electrode |
|
| voltage output (high voltage PWB). |
|
|
|
|
|
|
|
5 | Toner stirring roller |
|
| Lead toner to the developing roller and |
|
|
|
|
| charges toner. |
|
|
|
|
|
|
|
6 | Zenor diode |
|
| Maintains the potential between the |
|
|
|
|
| developing roller and the toner stirring roller |
|
|
|
|
| at a constant level. |
|
|
|
|
|
|
|
7 | Toner seal |
|
| Shields toner from leaking outside the |
|
|
|
|
| developing unit. |
|
|
|
|
|
|
|
8 | Potential control sheet |
|
| Maintains the developing roller potential at |
|
|
|
|
| a constant level. |
