| Zusammenfassung: | A roller member used in an image forming apparatus includes a metallic shaft. The metallic shaft includes a cylindrical portion formed so that one end portion and an other end portion of the metallic plate oppose each other and a projecting portion projecting from an end surface of the cylindrical portion outward in an axial direction of the metallic shaft. The projecting portion includes an end surface located at an end of the projecting portion in the axial direction and an inclined surface configured to connect the end surface of the projecting portion and the end surface of the cylindrical portion. The inclined surface is inclined with respect to the axial direction of the metallic shaft by extending outward from the end surface of the projecting portion in a circumference direction of the cylindrical portion. |
