As shown in Figure 1, developer housing 10 includes a chamber 12 having developer material therein. Chamber 12, in the lower region thereof, is divided into two compartments 14 and 16, respectively. Each compartment has developer material therein which must be crossmixed. Preferably, the crossmixing in each compartment will be in opposite directions. This may readily be achieved by a bead chain type of crossmixer, indicated generally by the reference numeral 18. The detailed structure of bead chain crossmixer 18 is shown in Figure 2. As depicted thereat, one portion of bead chain crossmixer 18 is positioned in compartment 18 with the other portion thereof being located in compartment 14. Bead chain crossmixer 18 includes a pair of opposed spaced sprocket gears 20 having bead chain 22 entrained thereabout. A plurality of substantially equally spaced disks 24 are secured to chain 22. A drive motor, coupled to gear 20, rotates gear 20 to advance chain 22 in the direction of arrows 26. In this way, disks 24 cause crossmixing of the developer material in opposed directions in the respective compartments 14 and 16 of chamber 12.
