Abstract

The present invention relates to a method of producing a plurality sets of prints from a plural-page original in an image forming apparatus having an endless transfer member onto which images are transferred from an image retaining member. The endless transfer member is operable to support a predetermined number (X) of images during one cyclic movement thereof. In this method, a first printing operation is executed in which the predetermined number (X) of images of a first page of the original are formed on the endless transfer member during one cyclic movement thereof when a desired number (Y) of sets of prints exceeds said predetermined number (X). Second, the first printing operation is repeated until a remaining number (M) of image(s) of the first page becomes less than said predetermined number (X). Third, a second printing operation is executed in which the remaining number (M) of image(s) of the first page and a calculated number (X-M) of image(s) of a second page of the original are formed on said endless transfer member during one cyclic movement thereof after the remaining number (M) of image(s) of the first page becomes less than the predetermined number (X).
