Abstract
A dual auger development apparatus for use in an electrostatographic reproduction machine such as copier or printer, includes a pair of identical single piece auger devices and each having a shaft and a plurality of integrally formed partial blade members so as to require no assembly of the blades to the shaft. Each auger device includes a radially extending cross-mixing vane which is integrally formed on the shaft. The cross-mixing vane formed as such is spaced circumferentially from the edges of the partial blades and extends continuously the full length of the shaft within the development housing. The cross-mixing vane includes a first length portion and a second length portion, The first length portion has a radial extension that is coextensive with that of the blade members and which is greater than that of the second length portion.
