Abstract
When documents fed by an automatic document feeder are subjected to the first copying operation, the documents are counted one by one. Alternately, the total number of documents are calculated by dividing the number of copy paper sheets sent to an intermediate tray, by the preset number of copies. Page entry is made in the copy paper sheets taken out from the intermediate tray, based on the total number of documents thus obtained. The total number of documents may be automatically counted. Accordingly, even though the documents are successively fed, starting from the last-page document, page entry may be made. The operator is not required to manually count the total number of documents.
