<p>An electrophotographic printing machine in which an electrostatic latent image recorded on a photoconductive member (10) is developed with a liquid developer material (32) having at least a liquid carrier with marking particles dispersed therein. The liquid developer material is advanced on a roll (28) from a supply thereof to the latent image at a development zone (72). Marking particles are moved through the liquid carrier onto the surface of the roll and a resilient blade (40) removes excessive liquid developer material from the roll prior to the development zone. The density of marking particles deposited on the roll is increased by means of an electrode (36, 74) positioned adjacent the roll within the supply of liquid developer material.</p> |
