PROBLEM TO BE SOLVED: To facilitate assembling, and to improve supporting accuracy by reducing the number of components for supporting a sleeve. SOLUTION: For the developer sleeve attaching method for attaching the developing sleeve 24 to a developing container 22, a distance between walls 30 and 31 is made longer than the length of a sleeve unit 21; and for both end walls 30 and 31, a magnet shaft supporting hole 30a and a magnet shaft supporting member attaching hole 31a for attaching the sleeve unit 21 are formed coaxially; and the sleeve unit 21 is arranged, so that the hole 30a and the hole 31a is coaxial with respect to a magnet shaft, and the developing sleeve 24 is slid; then a developing magnet 23 is fitted into the hole 30a; then a magnet supporting member 32 to be fitted to the hole 31a so as to support the magnet shaft 33 is inserted to the hole 31a; and the magnet shaft 33 is fitted into the hole of the magnet supporting member 32. |
