PURPOSE:To eliminate the generation of an uncomfortable squeaking sound during a paper separating operation and prevent a sheet of paper from coming in close contact with a rubber surface by embedding cork grains in such a way that they are exposed to the same plane as the surface of a roll type rubber member and forming said surface into a finely rugged surface. CONSTITUTION:The surface 1a of a rubber board 1 which forms a piled-feeding preventing rubber member, is buffed to form a finely rugged surface. And, part of cork grains 2 which are mixed in this rubber board 1, are exposed on this surface 1a, to prevent a squeaking sound from generating while separating a sheet of paper, and to prevent a mirror surface finished sheet from sticking to the surface 1a. |
