Abstract
Method and apparatus for electrophotographically imaging a photosensitive film in which a fractional area of the film, selected by automatic or preprogrammed access, is electrostatically charged and thereafter exposed to a pattern of radiation, is moved along a path of travel to a second location at which the latent image is developed by the application of toning fluid, and is preferably returned along the path of travel to fix or fuse the developed image as a next adjacent area is indexed for exposure. Additional areas of the film may be sequentially imaged by repeating the above sequence or by reinserting the partially completed film at a later time and addressing any desired used or unused area.
