Abstract

An image forming device including a memory for storing image data. The memory is prohibited from erasing the image data undesirably. When a user transmits the image data from a computer to the image forming device so as to obtain a plurality of copies of a document the image forming device, first, provides a first copy of the document. Also, the image data is stored in the memory. At this time, the image data is prohibited from being erased. Then, when the user wishes to obtain the rest of the copies, the user presses a continue key. On the other hand, when the user wishes not to obtain the rest of the copies, the user presses a cancel key. Then, the image data is allowed to be erased. When a predetermined time duration elapses without neither the continue key nor the cancel key is pressed, the image data is allowed to be erased.
