摘要

An image formation system includes image forming means for forming different color toner images on a recording material having a toner reception layer; first image heating means for heating and pressing the toner image on the recording material; second image heating means for heating and pressing the toner image on the recording material having been heated and pressed by the first image heating means; and wherein the first image heating means is operable so as to provide a granularity R of the toner image satisfying 0.5<=R<=4.0 and a glossiness G of the toner image satisfying 5<=G<=40, and the second image heating means is operable so as to provide a granularity R of the toner image satisfying not more than 4.0 and a glossiness G of the toner image satisfying not less than 60.
