ABSTRACT:
The sheet conveying roller includes a shaft member and a sliding portion arranged in the circumferential direction of the shaft member. The sliding portion is adapted to make sliding contact with the shaft member. The sheet conveying roller also includes an elastic member configured to fasten the sliding portion to the shaft member and makes contact with a conveyed sheet at an outer circumference thereof. The elastic member generates a frictional resistance between the shaft member and the sliding portion by a clamping force of the elastic member.
