With a structure in which gear trains 5, 6 of a developer supply container 1 are locked by a locking member 7, and the gear trains 5, 6 receive a drive from a gear 12 of a developer receiving apparatus 10, thus accomplishing automatic setting rotation of developer supply container 1, when the developer supply container 1 is once dismounted and then remounted, the locking member 7 is in a non-locking position, and therefore, the setting rotation of the developer supply container 1 cannot be effected automatically. With inserting operation of the developer supply container 1, an inducing portion 7c of the locking member 7 is pushed and raised by a guide portion 10j provided in a groove portion of the developer receiving apparatus 10, so that locking member 7 effects its locking operation. Therefore, upon completion of the insertion of the developer supply container 1, the gear trains 5, 6 are locked by the locking member 7, and therefore, the setting rotation of the developer supply container 1 can be properly effected.
