This disclosure relates to a self-biasing corona discharge device, for example, a dicorotron, which is suitable for use in conditioning the residual toner on a charge retentive surface, such as a photoreceptor, to thereby facilitate subsequent toner removal therefrom. The foregoing device is utilized in conjunction with a self-biasing detack corona device suitable for use in reducing electrostatic attraction between the copy substrate and the photoreceptor. The self-biasing arrangement used for conditioning the residual toner enables sufficient shield current to be generated to effect the preclean (i.e., residual toner conditioning prior to cleaning) function. The biasing arrangement used in the corona device for conditioning the residual toner is also utilized in connection with the charge and transfer coronode devices thereby permitting all of the corona devices to be powered by a single secondary winding of the power source at reduced power.
