Abstract

A system CPU sets a storage area in a page memory when a copying operation has been started. Where a clear/stop key, etc. is depressed to suspend the copying operation, the system CPU checks whether there is data in the page memory. If there is data in the page memory, the system CPU displays a selection screen on a message display section for selection as to whether the data in the page memory should be retained or released. Where “HOLD” is determined, the system CPU performs re-scanning and stores data in the page memory at the time the setting has been changed and the copying operation has been resumed. On the other hand, where “RELEASE” is determined, the system CPU releases the data in the page memory and performs re-scanning and stores data in the page memory at the time the setting has been changed and the copying operation has been resumed. Finally, the printing of the data in the page memory is resumed by a printer.

Claims

1. An image forming apparatus, wherein image data of a document is read, the read image data is stored in memory means, and the stored image data is used to form an image, the apparatus comprising:

interrupt means for interrupting a series of image forming operations beginning with reading of an image of the document and ending with completion of formation of an image;

discrimination means for determining, where image data is stored in the memory means, whether the image data is to be retained or erased, when the image forming operations have been interrupted by the interrupt means;

first control means for retaining, when the retention of the image data has been determined by the discrimination means, the image data stored in the memory means and, after the interrupted image formation operations are resumed, performing an image forming control with use of the retained image data; and

second control means for erasing, when the erasure of the image data has been determined by the discrimination means, the image data stored in the memory means and, after the interrupted image formation operations are resumed, reading image data of the document, storing the read image data in the memory means and performing an image forming control with use of the stored image data.
