Abstract
The present invention provides a particle dispensing apparatus comprising, an elongate transport guide apertured along its length; a transport device within the guide for transporting particles introduced through an entrance port into the guide and along the guide until they fall through the apertures to the outside of the guide; an elastic plate is secured to the guide, has a shaped edge portion partially covered with the opening area of the aperture in the guide and the guide is supported so as to be free to move in response to vibratory forces. When using this invention, since the transport guide is arranged so that it is free to move within the system such as the developer and can be vibrated slightly by the vibration due to the rotation of the developing roller in the developing system or the vibration of the developing system itself when operating, even if, by any chance, aggregated toner should block the apertures in the transport guide, this state can be broken down by this slight vibration of the transport guide.
