Abstract: A developer dispensing apparatus includes a coiled spring auger which is rotated through a developer bed in a direction to dispense developer through a dispensing opening. The spring auger has an unsupported free end which is non-fixedly placed over a hold down mechanism attached to one end of the developer housing and which projects inwardly into the toner bed. As the spring auger rotates a tendency of the free end to vertically rise from the developer is inhibited by making contact with the hold down mechanism. By proper configuration of the contacting surface of the hold down mechanism, a thumping or antibridging action is imparted to the toner by periodically causing the coiled end to wind and unwind storing and releasing energy along the developer bed length.
