Abstract An image forming apparatus (20) includes the following elements. A first obtaining unit (31) obtains a print request including image forming data which is used for forming an image for each of logical pages. An output unit (23) outputs a print medium on which an image is formed on the basis of the image forming data. A combining unit (31,32) obtains, in response to the print request, from an external device (40) that manages identifiers for specifying output numbers indicating a chronological order in which sets of logical pages are output, information concerning each of identifiers forming a set of identifiers that specify the logical pages corresponding to the image forming data and an output number indicating a chronological order in which a set of the logical pages is output, and combines the obtained information with an image formed on each of physical pages output by the output unit (23). A second obtaining unit (31) obtains information concerning each of the identifiers combined with the image formed on the print medium output by the output unit (23). A third obtaining unit (31) obtains, if execution of the print request has stopped, print request stop information indicating a reason why the execution of the print request has stopped. A sending unit (31) sends the information concerning each of the identifiers obtained by the second obtaining unit and the print request stop information obtained by the third obtaining unit to the external device (40) in association with each other.
