ABSTRACT:
A cylindrical member used as an electrophotographic photosensitive drum or a developing sleeve has a cylindrical surface with a high shape accuracy (straightness and roundness). In cutting the outer circumferential surface of a cylindrical work by cutting tools rotating around the work, clamp portions of a right work holder and a left work holder are inserted into the two ends of the work. The work is held by abutting these tapered surfaces against circular ridge portions formed in the inner edges of end faces of the work and pressing the work in the axial direction.
