Abstract:
1. An image forming system, comprising: an image forming apparatus that is equipped with a printer that prints an image on a sheet; and a post processing apparatus that performs a post process on a first job before performing a post process on a second job, each job comprising one or a plurality of sheets each carrying thereon an image printed by the image forming apparatus, and wherein: a sheet feeder that feeds a sheet of the first job before a sheet of the second job to be post-processed to a post processing position in the post processing apparatus; a timing judger that judges which is before/after, a first timing to finish feeding the last sheet of the first job to the post processing position so that a post process could be performed, or a second timing to finish making preparation of the post processing apparatus to perform a post process on the first job; a delaying time calculator that calculates a post process execution delaying time specific to the post processing apparatus and based only on the first job, which is a time difference between the first timing and the second timing, if the second timing is after the first timing; and a sheet feed controller that controls the sheet feeder to control sheet feed timing of the top sheet of the second job to the post processing position by using the post process execution delaying time calculated by the delaying time calculator, if the timing judger judges that the second timing is after the first timing, wherein the sheet feeder feeds the second job to the post processing position after feeding the first job to the post processing position.
