DEVELOPING DEVICE FOR XEROGRAPHIC COPYING MACHINES |
摘要 |
<p>Developing device for xerographic copying machines. Developing a xerographic toner image without the use of carrier beads is carried out by means of an applicator roller which transfers toner from a trough towards the image bearing medium via a scraper element mounted at the exit opening of the trough. An exact regulation of the amount of toner which is transferred in this way may be carried out by providing a DC-voltage between the transfer roller and the scraper. GV.1003</p> |
