ABSTRACT:
A copier for duplex copying in which blank sheets are fed from a copy sheet tray (41) to a photoreceptor (11) to receive a first image on one side and the simplex copy sheets so formed are conveyed to a duplex buffer tray (43) from which they are refed to the photoreceptor to receive a second image on the other side. The buffer tray (43) is arranged so that the simplex sheets are inserted into it lead edge first in the same direction (right-to-left) in the drawing in which they leave the photoreceptor and are refed trail edge first along a folded path between the buffer tray and the photoreceptor so that the sheets are inverted once between the buffer tray and the photoreceptor. As illustrated the buffer tray (43) is arranged beneath the photoreceptor and the copy tray (41) is arranged beneath the buffer tray (43). A double folded path (55) for returning simplex sheets to the buffer tray is provided between the photoreceptor and the buffer tray.
