Abstract

A device for containing a photoelectrophoretic ink between a pair of web electrodes is provided. In the drawing, there is shown imaging roller 1 over which there is entrained blocking electrode 3. Another web electrode 5 is brought into tangen-tial contact with the blocking electrode 3, thereby sand-wiching a coating of photoelectrophoretic ink previously coated on electrode 5. As blocking electrode 3 approaches imaging roller 1, an embossing roller 7 urges blocking electrode 3 into a groove 9 provided in imaging roller 1, thereby preventing seepage of the ink beyond the groove provided in imaging roller 1.
