Abstract
A developing system for an electrostatic copying apparatus has a primary spiral screw for conveying developer (including at least toner) in one direction with respect to the width of an area to be developed, and a secondary spiral screw arranged for receiving developers from the primary spiral screw and for conveying the received developers in a direction opposite to the conveyance direction of the primary spiral screw. The primary and secondary spiral screws have different conveyance capacities. An apertured receptacle mounted below the primary spiral screw feeds developers from the primary spiral screw to the secondary spiral screw.
