Abstract: A record processor employing a novel developing system, toner module and method in which a quantity of toner fluid is held adjacent to an electrostatic latent image on a film, in a substantially quiescent state, for a sufficiently long period to insure migration and adherence of toner particles to the image, is disclosed, wherein a set small quantity of fluid is drawn into a development chamber formed adjacent to the film which chamber is sized and shaped so as to facilitate the fluid reaching a relatively quiescent state quickly and which fluid is held in the chamber by a natural meniscus dam at a sharp edge formed across the flow path of the toner.

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.

Abstract: Disclosed is a method and apparatus for developing an electrostatic latent image on an electrophotographic film through use of a special developing chamber forming a passageway through which electrostatically charged toner particles are conducted to contact the film. The chamber has an opening bordered by a mask against which the film is placed to form a seal, an inlet through which toner particles and drying air enter the chamber, and an outlet through which toner particles and drying air leave the chamber. The apparatus further includes supply means for providing toner particles to the chamber, toner flow-control means for permitting a predetermined quantity of toner particles to flow through the developing chamber at predetermined times, air supply means for supplying drying air to the inlet of the chamber, and vacuum means connected to the outlet of the chamber for drawing the toner particles and air through the chamber.

Abstract: Disclosed is an improved apparatus for electrostatically charging an electrophotographic film held stationary with respect to a corona source. The improvement consists of a capacitor interconnecting the film to ground for limiting the amount of charge deposited upon the film during charging.

Abstract: Disclosed is electrical connective means for establishing electrical contact with an electrically conductive area on the surface of an electrophotographic film held on a carrier within an imaging apparatus. The imaging apparatus includes an enclosure within which the film is imaged, a carrier for holding the film while it is imaged, reciprocating means for moving the carrier to and from a load position near an opening of the enclosure and an imaging position within the enclosure. The electrical connective means includes an electrical contact member connected to the carrier for making electrical contact with the conductive area on the surface of the film, engagement means for moving the contact member into electrical contact with the conductive area in response to movement of the carrier from the load position to the imaging position, and disengagement means for moving the contact member away from the recording member in response to movement of the carrier from the imaging position to the load position.
