Method of recycling developing cartridge having holder assembly mounted on gear cover with screw

A method of recycling a developing cartridge,

• the developing cartridge including:
• a housing configured to store developer therein and extending in a longitudinal direction;
• a gear cover positioned at one end of the housing in the longitudinal direction;
• a holder assembly;
• and a first screw for mounting the holder assembly on the gear cover, wherein the holder assembly includes:
• a storage medium;
• a storage medium holder holding the storage medium, the storage medium holder being movable relative to the housing and the gear cover;
• and a holder cover holding the storage medium holder,
• the method comprising:
• a gear cover removing step of removing the gear cover having the holder assembly mounted thereon with the first screw from the housing;
• a screw removing step of removing, after the gear cover removing step, the first screw from the gear cover;
• a holder assembly removing step of removing, after the screw removing step, the holder assembly from the gear cover;
• a first gear cover mounting step of mounting, after the holder assembly removing step, the gear cover on a jig in a first direction in a state where another holder assembly different from the removed holder assembly is mounted on the jig, the another holder assembly including another storage medium holder and another holder cover;
• a holder assembly mounting step of mounting, after the first gear cover mounting step, the another holder assembly on the gear cover with the first screw;
• and
• a second gear cover mounting step of mounting, after the holder assembly mounting step, the gear cover having the another holder assembly mounted thereon with the first screw on the housing,
• wherein, in the first gear cover mounting step, the another storage medium holder of the another holder assembly is restricted from moving relative to the jig and the another holder cover of the another holder assembly in a state where the another holder assembly is mounted on the jig.
