Abstract

PURPOSE:To provide a manufacturing method of a high friction roller by which paper feeding accuracy is not deteriorated even if a roller having a projection slipping-out part caused by reducing a condition where a thickness of resin becomes nonuniform in a boundary part between a printing start position of ultraviolet-curing resin and a printing finish position is used as a paper feeding roller. CONSTITUTION:After screen printing is performed on an outer peripheral surface of a metallic cylinder body 11 by dividing ultravoilet-curing resin 14 in two or more times so that their boundary line 16 does not become parallel to the axial direction of the cylinder body 11, for example, so as to become an oblique line or the like to a zigzag line, a broken line or the axial direction, it is exposed and developed so as to become a prescribed dot pattern, and next, etching treatment is performed. Therefore, a large number of fine projections are formed on the outer peripheral surface of the cylinder body 11, and a high friction roller is manufactured.

Therefore, as shown in FIG. 7, the overlapping portion 14a of the ultraviolet curable resin 14 is thicker than the other portion 14b. Then, when the ultraviolet ray L is irradiated, the width w 1 of the light flux reaching the outer peripheral surface 13 of the cylindrical body becomes, for example, about 130 μm in the other portion 14b, whereas the light flux is narrowed in the overlapping portion 14a. , The outer peripheral surface 1 of the cylindrical body
The width w 2 of the light flux reaching 3 becomes, for example, about 90 μm.

As a result, the width of the resist formed in contact with the outer peripheral surface of the cylindrical body becomes extremely narrow at the overlapping portion 14a. By the way, the etching initially proceeds perpendicularly to the outer peripheral surface of the cylindrical body, but thereafter also proceeds in a direction of reducing the diameter of the formed protrusion. For this reason, if the width of contact between the resist and the outer peripheral surface of the cylindrical body is small, the projections become thinner and thinner, and the resist may peel off, resulting in disappearance of the projections.
