Abstract

PROBLEM TO BE SOLVED: To reduce maintenance costs by dispensing with the replacement of an entire part instantly when its performance is degraded, and make use of the non-defective portion of the part again as much as possible. SOLUTION: When the life of an outer side surface 3a for a rubber member 3 is found to have been nearly over, it can be determined by an operator that its life is nearly over based on a fact that the circumferential groove 31 of the outer side surface 3a is worn out so as to be shallow in depth. When the life of the outer side surface 3a is found to have been over, the rubber member 3 is removed from the rubber member fitting part 12 of a core member 1, the outer side surface 3a is broken into the inside, and is turned inside out so as to let an inner side surface 3b be turned out to be an outer side surface. By letting the rubber member 3 in this state be fitted again to the rubber member fitting part 12 of the core member 1, the paper contact surface of a paper feeding roller can be brought in a new article condition, so that the paper feeding roller can thereby be reused.
