Abstract

The latent image formed on a screened photoconductive member may be developed with an aerosol type of development system. One such type of development system is depicted in Figure 1. As shown thereat, a vacuum system (not shown) is coupled to conduit 12. Conduit 12 has an open area positioned closely adjacent to photoconductive member 10. Housing 14 has a slot therein to permit air to pass therefrom along conduit 12 to photoconductive member 10. Screen 16 carries the toner particles of container 20 and surrounds housing 14. The toner particles move in the direction of arrow 18 through conduit 12 into contact with the latent image recorded on photoconductive member 10. The latent image is developed by the flow of toner particles to form a powder image.

AN AEROSOL DEVELOPMENT SYSTEM (Cont'd)

The latent image formed on a screened photoconductive member may be developed with an aerosol type of development system. One such type of development system is depicted in Figure 1. As shown thereat, a vacuum system (not shown) is coupled to conduit 12. Conduit 12 has an open area positioned closely adjacent to photoconductive member 10. Housing 14 has a slot therein to permit air to pass therefrom along conduit 12 to photoconductive member 10. Screen 16 carries the toner particles of container 20 and surrounds housing 14. The toner particles move in the direction of arrow 18 through conduit 12 into contact with the latent image recorded on photoconductive member 10. The latent image is developed by the flow of toner particles to form a powder image.

An alternate development system is depicted in Figure 2. As shown thereat, toner hopper 22 stores a supply of toner particles therein. A rotating brush 24 is positioned in housing 26. Housing 26 is in communication with toner hopper 22 and has an exit port 28 therein for permitting air to exit therefrom. This results in the toner particles exiting housing 26 at opening 30 into conduit 32. Conduit 32 has an opened portion adjacent photocondu...
