Abstract

As shown in the drawing, development system 10 includes a developer housing 12 having a chamber for storing a supply of developer material therein. A bucket or paddlewheel 14 is positioned in the lower region of the chamber of housing 12 to advance developer material upwardly to developer roller 16. Developer roller 16 includes a plurality of spaced elongated magnetic members 18 which are mounted on elongated bars attached to spaced disks 20 which, in turn, are mounted on shaft 22. Shaft 22 is coupled to a suitable drive motor for rotation in the direction of arrow 24. Paddle wheel 14 rotates in the direction of arrow 26 to advance developer material in an upwardly direction to developer roller 16. Developer roller 16 advances the developer material into contact with the electrostatic latent image recorded on photoconductive drum 28. The residual developer material is removed from developer roller 16 and passes through crossmixer 30 downwardly to the lower region of housing 12 for subsequent recycling in the development system. Inasmuch as toner particles are continually being depleted
