Abstract

PURPOSE: To prevent a reduction in carrying force by providing line projections orthogonal to paper carrying direction on the surface of an elastic body roller, and forming the line projections into the line projections having a pitch less than 1mm and a top line width less than 0.5mm to minimize the contact area with paper at the time of friction.
CONSTITUTION: Line projections 11 orthogonal to paper carrying direction are provided on the surface of an elastic body roller 10. The line projection 11 has a triangular form of a pitch P less than 1mm, and a top line width less than 0.5mm, and the height H is also less than 1mm. The formation of such fine line projections minimizes the contact area with a paper even in unpolished state, making it difficult to adhere paper dust, and further, as the roller is never smoothed, a reduction in carrying force can be prevented.
