A rotatable stirring member for stirring a developer for conveying the developer is provided within a receptacle housing the developer. The stirring member can be subjected to elastically twisted deformation so that a shaft portion at the side of one end for receiving a rotation driving force can rotate in a phase which is advanced from that of a shaft portion at the side of another end.
