ABSTRACT:
Method and apparatus for applying liquid dispersed toner to the surface of an electrographic recording member, held on a platen which moves relative to a pair of coplanar cylindrical developing electrodes. Toner is deposited on the recording member by passing the record member over a projecting portion of each of the cylindrical developing electrodes in contact with a film of fluid established by the rotating coplanar cylindrical developing electrodes. The fluid has dispersed toner entrained therein and is supplied to the rotating cylinders by a pump which forces the liquid between each rotating cylinder and the shroud which surrounds the roller, except for an opening through which a projecting portion of each cylinder extends above its respective shroud. A dam connects the adjacent portions of the shrouds to collect additional fluid during the operation thereof and provides an elevated toner meniscus above and between the rotating cylinders, increasing the area of the fluid in the processing nip substantially. Wiper blades are provided along the length of each cylinder to remove residual material from the cylinders to insure that a renewed surface on each of the cylindrical developing electrodes is presented to the recording member.
