Abstract

PURPOSE:To constitute an electronic copier causing no malfunction in a device, transfer failure, or burning of a collecting toner, etc. do not occur, by preventing cut-off conductive fiber waste from going into a high voltage part. CONSTITUTION:Each charge removing brush 8c, 8d provided on the carrying path to a both surface tray 11 and the carrying path to a transfer part contacts with a sheet placed in the carrying process and removes the charge which has charged said sheet, and magnetic metallic fiber waste generated in this case is attracted and removed by permanent magnets 9a, 9b provided on this side of the transfer part, and it is prevented that said waste goes into a transfer charger 5. Also, in case when the fiber waste is carried with air flowing in a copier and has adhered onto a photosensitive body drum 1, the permanent magnet 9 removes it, therefore, such an accident as generates a spark in a charge removing charger 6 or a high voltage roller 7a in a cleaning unit 7 due to contact with the metallic fiber waste does not occur.
