ABSTRACT:
An apparatus in which a developer material is moved adjacent an electrostatic latent image so that the latent image attracts the developer material thereto in image configuration. The developer material is advanced from a supply thereof to the latent image, with the unused developer material being returned thereto. As the developer material returns to the supply thereof, the velocity in the central region is greater than in the marginal regions.
The foregoing is achieved by passing the unused developer mix through a plate having a plurality of progressively shorter chutes in an inwardly direction disposed symmetrically about the central region thereof. In this manner, the unused developer mix has a greater velocity in the central region than in the marginal regions thereof preventing the developer mix from clogging the chutes of the plate.
