Claim 6:
7. A power saving control method for an image forming apparatus, the power saving control method executing processing when a body controller of a body of the apparatus that interacts with a post-processing controller of a post-processor having a manual stapling function shifts the apparatus to a power saving mode, the power saving control method comprising:
receiving, while manual stapling is performed, a notification regarding conditions of stapling processing from the post-processing controller that executes the stapling processing on a sheet in response to detection, by the post-processor, of the sheet inserted in a sheet insertion opening for the manual stapling;
shutting off a power supply to a drive circuit and another circuit in the apparatus to shift the apparatus from a normal mode to a power saving mode when a predetermined shifting condition is satisfied;
when the shifting condition from the normal mode to the power saving mode is satisfied, determining whether the post-processor is in the conditions of the stapling processing on a basis of receiving the notification from the post-processing controller; and
instructing prohibition of the stapling processing and shifting the apparatus to the power saving mode when the post-processor is determined not to be in the conditions of the stapling processing.
