摘要： The specification discloses an electrophotographic image forming system. The system includes a photoconductor connected to a first electric potential constituting substantially an elongated cylindrical drum provided for rotating around an axis along an elongated direction of the cylindrical drum having an external charging surface disposed thereon. The electrophotographic system further includes a non-contact charger which includes a plurality of mutually insulated conductive films each having a sharp edge pointing perpendicularly to the charging surface. The non-contact charger further includes a packaging frame for securely attaching to and supporting the plurality of mutually insulated conductive films thereon. The plurality of mutually insulated conductive films are connected to a second electric potential different from the first electric potential for activating an electric discharge between the sharp edges of the conductive film and the charging surface.
