In an electrophotographic printing machine, it is highly desirable to have a readily removable developer housing. In this way, the resultant copy may be reproduced in different colors as well as reducing the assembly cost of the printing machine. As shown in the drawing, the modular developer housing has a developer roller 10 mounted rotatably in side plates 12 and 14. Augers 16 and 18 are also mounted in side plates 12 and 14. The motor (not shown) coupled to gear 20 drives developer roller 10. Gear 20 meshes with idler roller 22 which, in turn, drives gears 24 and 26. Gears 24 and 26 are connected to augers 18 and 20, respectively. In this way, as gear 20 rotates developer roller 10, idler gear 22 is driven to rotate gears 24 and 26 which, in turn, drive augers 18 and 20 in opposite directions.
