Method and apparatus for automatic "two-up" copying with intermediate latent image copiers

摘要: A copier of a type where an undeveloped electrostatic intermediate latent image from document sheet may be temporarily retained on retention member before being developed and transferred to copy sheet, with handling apparatus for sequentially feeding sheets individual copying, preferably automatically reordered in signature page order, system forming at least two closely circumferentially adjacent plural images copied documents, directly developing transferring these one pass onto side single sheet. Apparatus is also shown inverting representing the similarly receiving other thereof, repeating above steps form sets sheets.
