The invention provides a paper feed roller capable of reducing abnormal noise caused by a knurled shape while maintaining characteristics thereof, including maintaining friction coefficient and copingwith paper powder. The paper feed roller comprises a roller body formed of elastic material in a cylindrical shape and is characterized in that the roller body has protruding lines and recessed grooves obliquely extending relative to an axis of the roller body so that convex and concave portions having predetermined widths are alternatively formed in a circumferential direction of a peripheral surface, and the protruding lines have one-end side protruding line portions extending from a central part in an axial direction of the roller body toward one end thereof and other-end side protruding line portions extending from the central part in the axial direction toward the other end, and they are inclined relative to the axis in opposite directions.
