A replenisher for facilitating flow of toner in an electrophotographic apparatus. The replenisher includes a sump for receiving the toner. An beater element having a plurality of blades is rotatably mounted within the sump wherein some of the blades impart a shear force and a normal force along the axis of rotation to the toner while others of the blades impart a shear force and a normal force towards or away from the axis of rotation to the toner as the beater is rotated through the toner. This effectively &ldquo;aerates&rdquo; the toner and keeps it mobile within the sump.

Mechanism for agitating the toner in the replenisher of an electrophotographic machine

A mechanism for adjusting the location of a rotatable mixer and rotatable transport mechanism within the development station housing of an electrographic reproduction apparatus development station. The development station includes a housing, a rotatable mixer assembly located in a developer material reservoir within the housing, a developer device for applying developer material to an electrostatic image to be developed, a rotatable transport mechanism for moving developer material from the reservoir to the developer device, and a drive mechanism for rotating the rotatable mixer, the rotatable transport mechanism, and the developer device. The adjustment mechanism describes a first locating device for adjustably positioning the drive mechanism relative to the reservoir of the development station housing, and a second locating device for adjustably positioning the rotatable mixer and the rotatable transport mechanism relative to the development station housing. The second locating device includes a spacer member for maintaining a predetermined fixed distance between the rotatable mixer and the rotatable transport mechanism.
