Abstract:
1. An image forming system having an image forming apparatus, which forms images on sheets, and a sheet post-processing apparatus, which carries out a stapling process on the sheets having the images formed thereon by the image forming apparatus, and is configured to be able to shift into a power-saving state in which power consumption is lower than in a standby state in which image formation is not performed, comprising: a stapling unit configured to be able to carry out a manual stapling process in which sheets set by a manual operation are stapled independently of an image forming operation and an automatic stapling process in which sheets are stapled associated with the image forming operation, and to move along a path including a manual stapling position for the manual stapling process and an automatic stapling position for the automatic stapling process; a sheet setting unit into which the sheets on which the manual stapling process is to be carried out are set; a detection unit configured to detect that the sheets have been set into said sheet setting unit; a movement control unit configured to move said stapling unit to the manual stapling position when the sheet post-processing apparatus is to shift into the power-saving state; and a power control unit configured to, when it is detected that the sheets have been set into said sheet setting unit by said detection unit in a state in which the image forming apparatus and the sheet post-processing apparatus have shifted into the power-saving state, hold the image forming apparatus in the power-saving state and return the sheet post-processing apparatus from the power-saving state.
