发明名称 Method and apparatus of fabricating a photosensitive drum or fixing belt
摘要 <p>A method of fabricating a circular-shaped metal structure includes the steps of (a) rotating a pipe (4) around an axis thereof, the pipe (4) being composed of a plastic-workable metal, (b) moving a jig (6) towards the pipe (4) in a direction perpendicular to the axis until the jig (6) makes contact with an outer surface of the pipe (4), and compressing the jig (6) onto the pipe (4), and (c) moving the jig (6) in a direction in parallel with the axis with the jig (6) being compressed onto the pipe (4) while the pipe (4) is kept rotated, and is characterized by (d) measuring a thickness of a wall (4a) of the pipe (4) during the step (c), and (e) adjusting a pressure with which the jig (6) is compressed onto the pipe (4), in accordance with the thickness measured in the step (d). <IMAGE></p>
