Abstract
An image formation method wherein a thin film of a dyestuff liable to sublime or gasify is formed on a gas permeable film, and a heating element adjacent the back of the gas permeable film is heated in response to an image signal to generate from the dyestuff thin film a dyestuff gas flow which is representative of an image and which permeates through the gas permeable film so that the dyestuff deposits on acceptor paper adjacent the gas permeable film to form the image on the back of the acceptor paper.
