Abstract
A developer backer bar having a substantially flat surface 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 substantially flat surface eliminates or minimizes errors that may result from slight variations in axial alignment between the backer bar and the developer member.
