To provide a cylinder machining device with high surface accuracy and its machining method not leaving uneven cutting marks comprising a plurality of cycles after the cylinder surface is cut, or not forming images including periodic marks after the cylinder is manufactured as a photosensitive drum.
This cylinder machining device has a cylinder holding means for holding a cylinder to be machined, a cutting member positioning and turning means for positioning a cutting member into contact with a surface of the cylinder and turning it around the axis of the cylinder, a cutting member moving and holding means for holding the cutting member movably in an axial direction of the cylinder, a cutting member moving means for moving the cutting member, and a connection means for connecting the cutting member moving and holding means with the cutting member moving means. The connection means restrains the mutual positions of the cutting positioning and turning means and the cutting member moving means in the axial direction of the cylinder using fluid pressure, and connects the cutting member positioning and turning means with the cutting member moving means so that their mutual positions can freely move on a cross section perpendicular to the axis of the cylinder.
