An image formation device, having a storage unit capable of storing image data, includes a determination unit for determining the capability of another image formation device, and an editing unit for performing desired editing as to the image data to be stored in the storage unit. If the determination unit determines that the desired editing cannot be performed by another image formation device, the desired editing is performed by the editing unit and the image data subjected to the desired editing by the editing unit is transmitted to another image formation device. On the other hand, if the determination unit determines that the desired editing can be performed with another image formation device, the image data is transmitted to another image formation device without the editing unit performing the desired editing.
