Image forming apparatus capable of repeatedly reading out and printing stored image data

摘要

In order to efficiently utilize a memory in a digital copying machine which reads image data from an original and stores the read image data, whether or not to store image data in the memory is determined when the image data is read or the image data is input through an external interface. For example, image data read by an image reader is stored while data from an external device which is input through the external interface is not stored. This is because when the digital copying machine is used as an external device printer, the owner of the image data is difficult to identify and therefore the image data is not to be stored in the memory.
