Electrophotographic charging device |
摘要 |
A charging member for charging a photosensitive member from above toner in an electrophotographic process in which charging, exposure, development, and transfer steps are performed repeatedly and in which a step of cleaning toner remaining on a photosensitive member is eliminated, the charging member including: an electrically conductive charging wire which is disposed in contact with the photosensitive member; the charging wire forming an angle of less than 90 DEG with a direction of a rotational axis of the photosensitive member and is arranged at an interval in the direction of the rotational axis of the photosensitive member; and a power source for applying a pulse voltage to the charging wire, the pulse voltage having a polarity identical with that of the toner so as to vibrate the toner.
