This paper deals with the influence of surface contamination on the friction of rubber rollers. The powder or lint of paper which adhered onto the rollers after paper feed is one of the predominant causes of paper jams but the mechanism has not been understood. The purpose of this paper is to clarify the relationships between the friction force and the real contact area of papers and contaminated rubber rollers. Carrying out paper feeding tests by using a commercial multifunction peripheral, we tested different types of papers produced by different manufacturers. The tests have been done with combinations of different manufacturer's papers and different kinds of roller materials. Observations of the real contact area clarified that the roller surfaces covered with paper powders reduces the friction coefficient. Finally, we proposed a mechanism of paper jams caused by paper powders.
