Claim 3
Dependent Claim
126 words
In a development station of an electrographic apparatus having an elongate sump for receiving a supply of developer material and a magnetic brush for applying developer material to a photoconductor, a ribbon blender for mixing the material in the sump, the ribbon blender being rotatable about an axis and having an elongate helical ribbon positioned at least partially within the sump and extending along the sump, the ribbon having a plurality of convolutions spaced from each other along the axis, the improvement comprising: a wall secured to the ribbon, and extending generally axially from the ribbon, a plurality of partitions engaging the wall and the ribbon to form therewith buckets for picking up developer material in the sump and delivering such material to the magnetic brush.
Claim 4
Dependent Claim
