摘要： A magnet roller according to the present invention comprises: a single metal shaft member; and a pair of first and second semicylindrical resin magnet members each of which is shorter than the metal shaft member and has a first or second annular portion integrally provided at one end portion thereof. Each of first and second central holes is provided at the center of each of the first and second annular portions. The magnet roller according to the present invention is assembled by arranging the first annular portion and the second annular portion so as not face each other, inserting both end portions of the metal shaft member into the first and second central holes from the inner side of the first and second annular portions, and sandwiching the metal shaft member between the first and second semicylindrical resin magnet members in such a manner that both the end portions of the metal shaft member protrude to the outside of the first and second annular portions.
