MANUFACTURE OF ALUMINUM TUBE, ELECTROPHOTOGRAPHIC SENSITIVE BODY MANUFACTURED BY THE SAME PROCESS AND ELECTROPHOTOGRAPHIC DEVICE HAVING ELECTROPHOTOGRAPHIC SENSITIVE BODY

Japanese Patent JP2770870

B2

PURPOSE: To manufacture an aluminum tube high in out-of-roundness and adequate in surface roughness by working the tube under rolling pressure after the outer peripheral surface of the tube is cut.
CONSTITUTION: After the outer peripheral surface of the aluminum tube is cut, it is worked under rolling pressure. The cutting operation is performed by a cutting tool. Further, the cutting is performed by a centerless grinder. There or more rolling rolls are arranged obliquely to the axial direction of the aluminum tube to work the aluminum tube white rotating together with a rolling roll supporter. A photosensitive layer is put on the surface of the worked aluminum tube to form an electrophotography sensitizing body. In this way, it is possible to provide a picture high in quality.
