  • Patent number: 10571827
    Abstract: A device that replenishes developer to a developer unit and includes a storage for storing developer, an agitation member, and a vibration plate. The agitation member has a blade shape and is rotationally driven to agitate the developer in the storage. The vibration plate extends from a top portion towards a bottom portion of the storage along a rotation direction of the agitation member, and includes a vibration portion that vibrates due to contact with the agitation member undergoing rotation. A top end of the vibration plate is fixed and a bottom end of the vibration plate is a free end, and there is a gap between the vibration portion and an inner wall of the storage.
