Abstract: An image forming system includes an image forming unit, a post-processing unit, an acquiring unit, a first transmitting unit, and a post-processing control unit. The image forming unit forms an image on a recording medium. The post-processing unit is provided at a side for discharging the recording medium of the image forming unit and performs predetermined post-processing on the recording medium. The acquiring unit acquires a discharge timing at which the recording medium is discharged from the image forming unit. The first transmitting unit transmits a post-processing start signal corresponding to the discharge timing. The post-processing control unit causes the post-processing unit to start the post-processing when receiving the post-processing start signal from the first transmitting unit.
