ABSTRACT:
A developing device for a reproducing machine, in which a partition is arranged between a developer supply hopper and a developer bath which has a developing sleeve and developer agitating blades therein, arranged to face an image retainer. An aperture is formed in the partition and covered with an easily deformable thin elastic plate. The developer agitating blades in the developer bath are arranged in the vicinity of the apertures so that the elastic plate is vibrated when the developer projected by the rotation of the developer agitating blades is impinged to the elastic plate, thereby preventing the bridging of toner in the supply hopper.
