ABSTRACT:
There are disclosed a cylindrical member, constituting the main body of an electrophotographic photosensitive drum or a developing sleeve adapted for use in an image forming apparatus such as electrophotographic copying machine, laser beam printer, facsimile or printer, and a producing method therefor. A work obtained by cutting a tube, is worked to a predetermined internal diameter at the left-hand end, and is supported by an opening collet of the left arbor, while the other end is supported by a closing collet of the right arbor. A cutting tool holder, supporting a rough cutting tool and a finish cutting tool, rotates around the work at a high speed, and the work is moved axially by the table. Thus, the rough cutting tool and the finish cutting tool move in the axial direction of the work while rotating along the external curved surface thereof, thus cutting the surface.
