PROBLEM TO BE SOLVED: To provide a magnet roller which can assure ruggedness even if shafts are made of resin. SOLUTION: Thin cylindrical collars 15A and 15B are inserted between shafts 13A and 13B and bearings 14A and 14B of the magnet roller 10 in order to prevent a direct contact of the shafts 13A and 13B with the bearings 14A and 14B when a sleeve 11 is turned.
