Abstract
A fuser roller is obtained by heating a blank over predetermined regions starting from both the opening ends, and then necking the heated regions of the blank by moving a forming roller with rotation on the heated regions through the external pressing of the forming roller against the heated regions of the blank being rotated on its axis to draw form sidewalls integrally at both ends of a cylindrical body of the blank, respectively, and draw form cylindrical shafts integrally with the sidewalls, respectively. In this manner, the fuser roller can be fabricated using a single processing machine with respect to a single pipe member, which reduces equipment cost, further enhances production efficiency and implements low-cost production of fuser rollers.
