摘要： A process and apparatus for electrolytic etching of aluminum or its alloy is disclosed wherein an electric current is passed between an anode and a cathode which are spaced opposed in an electrolytic bath with a workpiece removably supported on an insulating frame so that the side of the workpiece to be etched faces the cathode, the insulating frame being disposed between the anode and the cathode and having at least one opening formed therein.

摘要： A toner sealing material for use in a toner cartridge of an electrophotographic image formation apparatus is disclosed. The toner sealing material comprises an elastic layer which is in contact with the cartridge via an adhesive layer and a tetrafluoroethylene resin porous layer having a thickness of at least 0.2 mm which is laminated on the elastic layer via an adhesive layer and is in contact with a developing roller fixed to the cartridge. With the sealing material, a toner can be prevented from leaking from a toner cartridge for an extended period of time.
