Image receiving sheet having particular critical surface tension, viscoelastic, and rockwell hardness characteristics and image receiving apparatus using the same

摘要

An image forming apparatus for forming an image in a receiving sheet by embedding toner in an image receiving layer formed on a base of the receiving sheet. The image forming apparatus uses a toner having an external additive, 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 viscoelastic characteristic such that its storage modulus (G') is between 1x102 Pa to 1x105 Pa and its loss modulus (G'') is between 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 phtalate. Still further, the image receiving layer has a Rockwell hardness (R scale) HRa of 121 or lower.
