A particulate image developer material mixing system for a reproduction apparatus, with a rotatably driven helical mixing coil in a developer material sump for mixing the developer material in the sump, and with a system for holding the rotatably driven helical mixing coil in the sump, and a system for anti-bridging of the developer material by agitating the developer material in the sump by agitating the mixing coil; including a smoothly rounded rod substantially extending inside of the helical mixing coil with a smoothly enlarged diameter end portion outwardly radi uses to operatively intermediately engage the mixing coil so that as the helical mixing coil is rotatably driven at least one coil thereof is periodically partially detained and deformed on the smoothly enlarged diameter end portion and then periodically released automatically after a further rotation, so as to provide a periodic anti-bridging agitation of the developer materials, at a desired frequency, and the free end of the helical mixing coil is a sealed coil, and the adjacent rod mounting plate is enlarged to prevent the coil from catching or interleaving on the rod on the mounting plate. |
