An image is formed in a receiving sheet by embedding toner in an image receiving layer on a base. The distribution of molecular weight of resin in the image receiving layer measured by gel permeation chromatography (GPC) of soluble matters of tetrahydrofuran (THF) has at least two peaks or shoulders. And the critical surface tension of the image receiving layer is made to be smaller than the critical surface tension of external additive. Further, the image receiving layer has a thermal characteristic such that a storage modulus (G') of 1x102 Pa to 1x105 Pa and a loss modulus (G'') of 1x102 Pa to 1x105 Pa at temperatures at which the toner is fixed. Furthermore, the image receiving layer contains an aromatic ester compound, more preferably the aromatic polyester compound being dialkyl phthalate. Still further, the image receiving layer has a Rockwell hardness (R scale) HRa of 121 or lower.
