Abstract
A method of recycling a support material for supporting images thereon, at least part of the support material including a paper layer which contains cellulose fibers as the main component and bears thereon hydrophobic images having a coloring agent and a heat softening or thermofusible material, includes the steps of causing the support material to hold a water-containing image peeling liquid thereon; bringing an image peeling member into contact with the hydrophobic images while the image peeling liquid is held on the support material; and peeling the hydrophobic images off the paper layer, with the image peeling liquid being held in an amount of 1.0 g or more per A4-size paper layer, or with the rate of the penetration of the image peeling liquid into the paper layer of the support material being set at 12 ml/m.sup.2 or more for a contact time of 0.4 seconds in which the image peeling liquid is in contact with the paper layer, or with the contact angle of the image peeling liquid with respect to the hydrophobic images being 100.degree. or less.
