Abstract

Disclosed is an improved electrophotographic developer tribo cage design which has a sample chamber held together with a ''screw top" fastening means. Tribo cage designs are known, for example, of generally cylindrical shape with a internal cavity for the developer formulation and partially open ends that provide for entrance and exit ports for blow off air and developer, respectively. The known design utilizes a slotted "tine-in-groove" fastening means. This design suffers from a tendency to leak carrier particles around the joining surfaces, particularly when very small carriers of the type used in color developer formulations are tested, and which leakage tends to distort the test results. The wall thickness of the improved tribo cage design preferrably has a thickness of from 2.0 to about 4.0 millimeters.
