Abstract
A developer electrode and reverse roller assembly are provided for use in conjunction with the rotatable print cylinder of a high speed electrophotographic printing press. The normal tendency of toner particles to stick to the developer electrode is inhibited due to the velocity by which toner dispersion is fed to the developer electrode. A pair of slots formed in the electrode face ensure that uniform amount and constituency of the dispersion are supplied to the print cylinder. Both the developer electrode and reverse roller assembly are pivotally mounted adjacent the cylinder with the reverse roller comprising a location sensor to sense reverse roller position and to stop the print cylinder when the reverse roller is not in proper position.
