摘要：A development apparatus having an active airflow system for generating negative air pressure to create an airflow out of a developer housing, drawing airborne contaminants from the developer housing. A developer system includes a plurality of developer housings being selectively moved into operative and inoperative poitions for development of a latent image on a photoconductive surface. As each developer housing is moved into and out of its operative position, an air duct is rotated in response to this movement for interfacing with, or sealing off, airflow through the housing, as appropriate. An apparatus of this type is used in a multi- color electrostatographic printing machine where succesive latent images are developed with different color developer material, thus preventing respective color developer materials from intermingling during the development process.
