Title: Electrifying device of electrophotographic copying machine
Inventor: YAKABE YUTAKA
IPC: G03G15/02
Filed: 1982-01-14
Abstract: PURPOSE:To make electrifying width variable, by selectively applying the voltage to electrifying brush divided and placed in the axial direction of a photosensitive drum. CONSTITUTION:An electrifying brush is constituted by embedding core wires 8''1-8''7 formed by covering a carbon fiber with an insulating layer, into conductive plates 8'1-8'7, and is placed in the axial direction of a photosensitive drum so as to be in contact with the surface of the drum. Between a copying operation of the first sheet and the following copying operation, it is necessary to stop electrification of the surface of the photosensitive drum, therefore, when voltage 9 is applied to the electrifying brush, it is cut off by turning off switches 101-104. In this case, lower voltage than that of a regular corona electrifier is used because of brush electrification, therefore, switching is executed easily. When executing reduction copying, it is necessary to narrow the electrifying width, therefore, the switches 101-103 are turned off in accordance with size.
