Abstract
A developer backer bar having a surface having a plurality of radii for interfacing with a noncontact developer member. The backer bar is arranged so that it can be retracted for clearance purposes when removing or inserting a xerographic CRU. Upon installation of the CRU, the backer bar is biased into position to maintain a development zone within predetermined parameters. The multiple radii surface eliminates or minimizes errors that may result from slight variations in axial alignment between the backer bar and the developer member while additionally providing low drag forces on the photoreceptor.
