Abstract
A new and improved structure for agitating the developer in the sump of a developer apparatus. To this end one or more magnetic steel shim or blade members are provided in the developer sump adjacent the outlet thereof and in the vicinity of a magnetic developer roll. The shape and location of the shim or blade members in the developer sump are such that a transport magnet (i.e., developer roll) rotatably supported adjacent the outlet of the sump causes vibration of the shim or blades due to the coupling and decoupling therebetween of the magnetic force fields created through the rotation of the developer roll.
