    摘要： Projections 4-formed on a circumferential surface of a roller portion of the sheet feed roller comprise straight grain projections whose projecting direction faces to the rotation direction of the roller portion, and reverse grain projections that are formed in a direction opposite to the surfaces of the straight grain projections. The straight grain projections are formed so as to be adjacent to each other in the axial direction of the roller portion, that is, in the direction of arrow B and are also formed in two or more rows in the circumferential direction of the roller portion, that is, in the direction of arrow A. The reverse grain projections are formed so as to be adjacent to each other in the axial direction of the straight grain projections and are also formed in the circumferential direction.
