PROBLEM TO BE SOLVED: To improve parts accuracy and assemblability by adopting two of shaft member respectively in the same shape being shorter than a magnet roll, and making respective flange on a sleeve both end as common parts. SOLUTION: In this magnet roll 12 for developing, since the shaft 34 supported rotatably by the shaft hole in the flange 30 is fixed with one end section of the magnet roll 18, and the shaft 36 fixed in the shaft hole of the flange 32 is supported rotatably by the other end of the magnet roll 18, the magnetic roll 18 by the shaft 34, and the sleeve 20 by the shaft 36 respectively is made possible to be independently rotatively driven. Moreover, the need of the shaft member penetrating the magnet roll 18 is eliminated by adopting two shafts 34 and 36 in the same shape, and respective length of shafts 34 and 36 can be composed shorter than the conventional shaft member, therefore the parts accuracy can be raised. Moreover, the number of component can be reduced by respective making two of flanges 30 and 32, and the shafts 34 and 36 in the same shape. |
