In a structure in which a gear train 5, 6 of a developer supply container 1 is locked by a locking member 7, and by the gear train 5, 6 receiving a drive from a gear 12 of the developer receiving apparatus, the setting rotation of the developer supply container 1 is automatically carried out, the setting rotation of the developer supply container 1 is not possible if a releasing projection 5a is at a position interfering a locking member 7. In view of this, the gear 5 is rotated to effect the locking member 7 to lock by abutment of an engaging portion 5d of the gear 5 to an engaging portion 13a of the developer receiving apparatus 10 with inserting operation of developer supply container 1. Therefore, upon completion of the insertion of the developer supply container 1, the gear train 5, 6 is locked by the locking member 7, and therefore, the setting rotation of the developer supply container 1 can be carried out properly.
