ABSTRACT:
A dual augar development apparatus for use in an electrostatographic reproduction machine such as copier or printer, includes a pair of identical single piece auger devices mounted therein and each having a shaft and a plurality of integrally formed blade members so as to require no blade-member-to-shaft-assembly. A last blade member includes a cross-transfer member connected thereto and integrally formed therewith. The blade members are semi-elliptical and form a single straight row of such members on the shaft. The row is aligned circumferentially so as to result in intermittent augering of developer material in the development apparatus.
