In an image processing system in which a plurality of image processing apparatuses and a management apparatus are connected to each other via a network, the management apparatus forms the image processing apparatuses into one or more groups based on apparatus attribute information, acquires control variable value information from an image processing apparatus in a group, and sends the acquired information to the other image processing apparatuses in the group. The other image processing apparatuses receive the control variable value information sent from the management apparatus, and execute image processing based on the received information.
