摘要： A copier comprises a photosensitive member substantially in the form of an endless belt and composed of a flexible base subjected to electric conductive treatment, and inorganic semiphotoconductive layer and organic semiphotoconductive layer superposed on the base; an exposure station for exposing the electrically charged sensitive surface of the photosensitive member to reflected light from the face of an original document to form an electrostatic latent image thereon; drive means for driving the photosensitive member during each cycle of transfer operation; means for driving transfer paper in synchronism with the travelling photosensitive member formed with the latent image so as to bring the paper into fitting contact with the member, the transfer paper being composed of an electroconductive base and a dielectric coating thereon; means for electrically grounding the bases of both photosensitive member and transfer paper fitted together to transfer the electrostatic latent image onto the transfer paper; and developing means for supplying toner to the transfer paper bearing the transferred electrostatic latent image to visualize the image. The copier further includes color separation filters in the exposure station and developing sections for three or four colors to be operated in accordance with the change of the filters. A color copy is obtained by repeating a copying cycle three or four times.

摘要： In an electronically controlled electrostatic latent image transfer type photographic duplicator, an original document receiver having a transparent plate for supporting an original document thereon is movable along the top surface of the duplicator case. An optical exposure projection system is mounted within the case and includes exposure and image slit openings. The original document receiver is reciprocated along the top surface of the duplicator case to completely expose the original document as it moves in one direction traversing the slit opening. A photosensitive plate reciprocates along a path parallel to and spaced from the original document receiver and is reciprocated at the same speed and in the same direction as the document receiver so that an image of the original document is projected onto the photosensitive plate as it moves in the same direction as the document receiver to completely traverse the image slit opening. The electrostatic latent image formed on the photosensitive plate is transferred to a transfer paper having a conductive base and an image transfer surface by contacting the transfer surface with the electrostatic latent image on the photosensitive plate as both the contacting portions of the transfer surface and the photosensitive plate move at the same speed and in the same direction. The transfer paper is deposited on the photosensitive plate so that its leading edge overlaps the leading edge of the photosensitive plate and is separated therefrom by a separating mechanism which includes a guide plate having a surface extending into the plane of the path of the photosensitive plate and including thereon comb-like projections. A member rotatable to a first and second position also includes comb-like projections and is biased into a first position wherein the comb-like projections are upstanding in the path of the transfer paper and the member is rotated to a second position by contact with the leading edge of the photosensitive plate having comb-like projections on the leading edge thereof; with the rotating member in the second position, its comb-like projections, as well as the comb-like projections on the photosensitive guide plates, are in interleaving relationship to form a continuous surface for guiding the transfer paper to a developing means. The image on the transfer paper is developed by contacting the transfer surface thereof with a developer. In one embodiment, the transfer paper is transported across a developing tank in close proximity to an electrode plate by an endless belt. In another embodiment, the developing tank is divided into two compartments separated by a weir and developer is pumped into one compartment and flows to the other compartment whereupon it flows over an electrode plate having wires on the surface thereof which have a height slightly less than the flow of developer. The transfer surface is carried across the electrode plate at a greater speed than the flow of the developer stream. The developed image is fixed by removing excess developer from the transfer paper by squeezing it between one or more squEeze rollers, respective ones of which may be in contact with a hygroscopic roller and a cleaning roller. The transfer paper is then dried by guiding it in close proximity to a heater and a blower. In a modification of the fixing mechanism, the squeeze rollers are caused to be separated in the absence of transfer paper therebetween. Additional developer may also be removed from the transfer paper by a rotating wiper roller the surface speed of which is greater than the speed of the transfer paper passing from the electrode plate, or a doctor blade which scrapes the transfer surface.
