Claim:
An image forming apparatus having an image processing unit that performs image processing based on image data acquired from another image forming apparatus, comprising: a first request unit adapted to request that the other image forming apparatus transmits image data stored in the other image forming apparatus and holds copy data copied from the image data; a reception unit adapted to receive the image data transmitted from the other image forming apparatus; a storage unit adapted to store the image data received by said reception unit; a determination unit adapted to determine whether or not a job having priority higher than the image processing is generated during execution of the image processing by the image processing unit based on the image data stored in said storage unit; an erase unit adapted to erase the image data stored in said storage unit in a case that it is determined by said determination unit that the job is generated; and a second request unit adapted to request the other image forming apparatus to transmit the copy data after the job is processed, wherein the image processing unit restarts the image processing based on the copy data transmitted from the other image forming apparatus in response to the request by said second request unit.
