Abstract

In tacky-image development, a liquid may be selectively charged onto a donor roll. The original document is illum-inated, and light reflected therefrom makes a photoconductive screen disposed in front of a corona generating device conductive. In this way, the informational areas of the liquid are charged. Heat evaporates the non-charged areas. The liquid is transferred to a sheet of paper and subsequently decorated with toner particles. An alternate mode employs a corona squeegy effect to generate film in the charged areas and thick film in the non-charged areas. Still another embodiment employs selective evaporation using a frost gravure effect and a donor roll.
