Abstract
An electrostatically charged image is applied to a smooth surface and moved past a development zone in which a carrier sheet perforated with a multitude of bores is also located. A layer of developing liquid is applied under gradually increasing pressure to a first surface of the carrier sheet so that the applied liquid squeezes through the bores to and beyond a second, opposite surface of the carrier sheet. The liquid emerges above the opposite surface of the carrier sheet to produce a multitude of part-spherical bulges. Field concentration occurs on the part-spherical surfaces of the individual tiny bulges. The first surface of the carrier sheet preferably exhibits lyophilic characteristic to the developing liquid, while the second surface exhibits lyophobic characteristic.
