In case of forming images by distributing image data mixedly including plural different kinds of data to plural image formation apparatuses, the data is distributed in consideration of a state of the image formation apparatus and data desired by a user is quickly output. In order to operate a system smoothly, an image formation system, which has an information processing apparatus capable of selectively transmitting a series of image data composed of plural pages containing first-kind image data and second-kind image data different from the first-kind image data to a first image formation apparatus and a second image formation apparatus in the page unit, controls to transmit the first-kind image data to the first image formation apparatus and transmit the second-kind image data to the second image formation apparatus from the series of image data. Further, transmission timing of the first-kind image data to the first image formation apparatus is made differ from transmission timing of the second-kind image data to the second image formation apparatus in accordance with a function of the first image formation apparatus or a function of the second image formation apparatus.
