Abstract
An image forming apparatus includes: a post-processor including a sheet detection circuit detecting a sheet inserted in a sheet insertion opening for manual stapling, a staple mechanism executing stapling processing on the sheet, and a drive circuit actuating the staple mechanism; a post-processing controller operating the drive circuit in response to detection of the sheet; a power circuit supplying power to the drive circuit and another circuit in the apparatus; and a power saving controller shutting off a power supply from the power circuit to the drive circuit and the other circuit and shifting from a normal mode to a power saving mode when a shifting condition is satisfied. Prior to shifting, the power saving controller checks the post-processing controller whether the stapling processing is currently executed, and, when the stapling processing is not currently executed, instructs prohibition of the stapling processing and shifts to the power saving mode.
