An image forming apparatus |
摘要 |
The opposing electrode has an opposing portion facing the peripheral surface of the toner support and a brush portion formed of a partial circumferential surface continuous to both ends of the opposing portion. The opposing electrode is rotated about a rotary axis disposed at the center of the partial circumference forming the brush portion. When the opposing electrode rotates, the brush portion comes into contact with the undersurface of the control electrode. The opposing electrode is applied with a high voltage, e.g. 2 kV from a high-voltage power source so that the brush portion can remove the toner adhering to the control electrode. <IMAGE> |
