Abstract
An applicator and method for applying liquid dispersed toner to the surface of an electrographic recording member, held on a platen which moves over a planar developing electrode, in which there is relative movement between the developing electrode and the recording member alternately in opposite direction, and in which there are at least two coplanar developing electrodes having toner fed therebetween, such as by a roller, and in which there are control means such as varying the direction of rotation of the roller to cause the developer to flow over either one or other of the developer electrodes according to the direction of relative movement of the platen.
