摘要

PROBLEM TO BE SOLVED: To obtain an electrophotographic sensitive body which enables formation of superior image free of interference fringes, moire, image stripes, half-tone unevenness, and a black spot on a white back ground, has no image defect in any environment, and has small potential variation and superior electrophotographic characteristics and its manufacture, the surface machining method for the cylindrical member for electrophotography, and a process cartridge which has the electrophotographic sensitive body and an electrophotographic device.;SOLUTION: In a magnetic field produced by a tool which has an N pole and an S pole, a magnetic body and abrasives are put, a cylindrical member to be machined is arranged in the area where the magnetic body and abrasives are present; and the tool and cylindrical member are moved relatively to each other and then the magnetic body and abrasives which are moving or stationary, and the cylindrical member are moved relatively to polish the outer peripheral surface of the cylindrical member.;COPYRIGHT: (C)2000,JPO
