ABSTRACT:
An image forming apparatus of this invention has a sorter which includes a first document tray on which first documents are placed, a second document tray on which second documents are placed, and two paths which can be switched. When an interrupt copying mode is selected, copies relating to the second documents can be sorted through a path which is different from the path employed for copies relating to the first documents. Even if a great number of copies must be produced and a plurality of copies must be obtained from a plurality of original documents, the wait time can be reduced and the efficiency of the copying operation of the image forming apparatus can be enhanced. Mixture of copies relating to two different original documents can be prevented, and the original documents can surely be separated. Therefore, complexity of copying operations can be relaxed.
