Title: Cleaning pad and electrifying device using that cleaning pad
Inventor: KAWAGOE HIROSHI
IPC: G03G21/10
Filed: 1994-03-31
Abstract: PURPOSE:To obtain a cleaning pad excellent in cleaning performance and durability by laminating a thin cleaning layer comprising a wear-resistant material and a thick supporting layer comprising an elastic material for use. CONSTITUTION:The cleaning layer 2 consists of a wear-resistant material and is brought into contact with an electrifying wire W of an electrifying device. The supporting layer 3 consists of a soft elastic material having high elasticity such as foamed neoprene rubber and is joined to the back side of the cleaning layer 2. The supporting layer 3 deforms with the cleaning layer 2 due to the contact pressure with the electrifying wire W to increase the contact area of the cleaning layer 2 to the electrifying wire W. Since the contact area increases as above described, the cleaning performance for the electrifying wire is improved. Further, since only the cleaning layer 2 comprising a wear- resistant material is brought into contact with the electrifying wire W and the cleaning layer 2 has high durability, production of breaks in the cleaning pad 1 can be prevented.
