ABSTRACT:
The sharpness and contrast of reversed images obtained by pressure-fixation of electrostatically developed copies of negative transparencies is provided by dissipating the electrostatic latent image after the development step but before the pressure-fixing step. The process finds application in microfilm reader/reproduction devices.
