<p>An electrostatic latent image development method and apparatus, includes a process nip (59) formed by operative engagement of first (10) and second (40) movable members for positioning a thin layer (58) of liquid developing material (54) in pressure contact with an electrostatic latent image which generates imagewise electric fields across the layer (58) of liquid developing material in the process nip (59). The process nip (59) is defined by a nip entrance and a nip exit, wherein the process nip and the nip entrance are operative to apply compressive stress forces on the layer (58) of liquid developing material thereat, and the nip exit is operative to apply tensile stress forces to the layer of liquid developing material, causing imagewise separation of the layer of liquid developing material corresponding to the electrostatic latent image. The layer (58) of liquid developing material is defined by a yield stress threshold in a range sufficient to allow the layer of liquid developing material to behave substantially as a solid at the nip entrance and in the nip (59), while allowing the layer of liquid developing material to behave substantially as a liquid at the nip exit. <IMAGE></p> |
