Abstract
In the distribution copy mode, when plural sets of copies are selected, a copying machine C1 of a transmitting end checks the status of copying machines C2 and C3 being connected through a communication line based on status information data. As a result of this check, if both of the copying machines C2 and C3 are set in the idle state, the number of copies specifying data and the image data are transmitted to be distributed to each copying machine. In the described arrangement, since one copy job can be divided to be distributed to plural copying machines, an improved productivity of copy operation and more effective use of the copying machines can be achieved.
