A method of forming a positive image on a surface comprises the following sequence of steps: (a) forming a first coating of sulphur on the surface, (b) exposing the first coating to imagewise electromagnetic radiation, (c) wiping the first coating, for example with rayon wool, thereby altering a characteristic of the radiation-struck areas relative to the areas not struck by radiation, (d) applying a second coating of sulphur over the first, and (e) developing the re-coated surface with a dry particulate material, such as a toner of the kind used in xerography.
