Abstract:
1. A discharger comprising: a discharger main body that is disposed so as to face a discharged portion of an image forming apparatus and is adapted to be attached to and detached from a holding member of the image forming apparatus body; a first electrode member that is supported by the discharger main body and is formed of a wire rod; an electrode cleaning member that contacts with and cleans the first electrode member; a detected portion that is integrally disposed to the electrode cleaning member; a detecting member that detects the detected portion while the electrode cleaning member is in a predetermined reference position; a cleaning member conveyer that conveys the electrode cleaning member along the first electrode member in both directions which toward and away from the reference position; and a movement control unit that controls a movement of the cleaning member conveyer by the conveyer, wherein the movement control unit controls the conveyer to move the electrode cleaning member away from the reference position when the discharger main body is mounted on the holding member until the detecting member does not detect the detected portion, and then after moving the electrode cleaning member away from the reference position in a front-and-rear direction, said movement control unit controls the conveyer to move the electrode cleaning member toward the reference position.
