Provided is an image forming system in which a plurality of image forming apparatuses are connected through a network, the image forming system including a control unit that controls the image forming apparatuses, wherein when a plurality of image forming apparatuses output a job requested in an arbitrary image forming apparatus, the control unit compares image quality parameters, such as a tone, a density balance, and a line width, in the image forming apparatuses, selects image forming apparatuses that have image quality parameters similar to each other and that can output the job, and causes the selected image forming apparatuses to output the job.
