ABSTRACT:
A digital copying machine capable of two-sided copying, which forms an image on one side of a paper sheet, transports the paper sheet through a sheet re-feeding path provided with a sheet turning over unit, forms an image on the other side of the paper sheet, and finally delivers the paper sheet outside. When two-sided copy mode is set in accordance with an instruction from the user, paper sheets are supplied at sheet intervals shorter than sheet intervals at which paper sheets are supplied in one-sided copy mode.
