Abstract
Abstract A modular imaging electrode transport assembly for use in forming photoelectrophoretic images in automated imaging machines. The unit has one tank for each roller electrode and electrical coupling means at each roller. A carriage shuttles the tanks back and forth past a contact position and each tank raises and holds the roller in the contact position while it functions in the imaging process so that the roller contacts an imaging member of the machine in which it is located in order to form a suspension image.
