ABSTRACT:
An image forming apparatus for obtaining a dye image on an image receiving material by applying an image forming solvent to a heat development photosensitive material and/or the image receiving material comprises: a solvent application device for applying the solvent to the heat development photosensitive material and/or the image receiving material to circulate and reuse the solvent; and a cation exchanger and/or a pollutant adsorbent disposed in the solvent application device so as to come into contact with the solvent. Accordingly, since Ca.sup.2+ ions, Mg.sup.2+ ions, etc., can be removed, the apparatus effectively prevents the fouling of the solvent.
