ABSTRACT:
A layer of fresh colorant is deposited on a first drum. Solvent is selectively deposited on a second drum in contact with the colorant layer in response to an electrical signal representing the density of a picture element. The colorant layer is subsequently brought into contact with first the solvent on the second drum and then with a recording medium to transfer the portion of the colorant layer which contacts the solvent to the recording medium.
