ABSTRACT:
A cylithographic copying apparatus includes a coil comprising continuous webs if imaging sheet and intermediate developer sheet formed in a spiral having alternating layers of imaging and intermediate developer sheet. The laminate formed of imaging and intermediate developer sheet is payed out from the coil past a developer station, where it is image-wise exposed, and through pressure rollers which form an image on the intermediate developer sheet. The intermediate developer sheet is conveyed to an assembling station where the imaged developer layer is transferred to a sheet of plain paper. In a preferred embodiment, the imaging sheet includes a support of polyethylene terephthalate (PET) and the intermediate developer sheet includes a substrate of aluminized PET. The coil preferably is rotatably mounted within a cassette which also includes a take-up spool for the spent imaging sheet; the cassette is easily insertable and removable from the copier housing.
