Abstract
An electrostatic recorder or copier that includes a vise which provides a variable clamping force to a recording medium, thereby capable of squeezing it between an applicator and a backplate. The vise is an expandable bladder expanding and retracting in response to fluid pressure. In this manner, movement of the recording medium may be prevented while purging toner from the applicator. A cross member is provided that is spaced apart from the applicator and the bladder is attached to it. The bladder includes a metal surface, which faces the applicator, capable of conforming to the profile, or irregularities, of the toning surface. The metal surface may be connected as an electrically grounded electrode and may include a single sheet of thin metal or a plurality of segmented metal sheets or plates.
