In successively copying a plurality of continuous pages of a book original by means of a copying apparatus adapted to print images of the pages on opposite surfaces of each copy sheet, a printing operation is controlled in such a manner that a series of processes including, illumination of the pages, charging and exposing of a photosensitive drum, developing, fixing and transfer printing of visible images, and ejection of printed copy sheets is automatically performed, if the book original is opened at desired pages and placed on an original placing glass plate of the copying apparatus in a normal condition in which the top of the book original is remote from the operator. With the operator merely turning the pages, the control method enables the production of a bundle or bundles of duplicate copies of the pages of the same order and arrangement as the book original, regardless of whether the book original is bound on the left side or on the right side and whether the first and last pages to be copied have even numbers or odd numbers. In copying the adjacent two pages, two pages can be copied in separate copying processes or in a single continuous copying process for the two pages.
