    Our interest exists on the understanding of viscoelastic properties of polymeric surfaces by means of nanorheology atomic force microscopy (AFM). In analyzing the force curve using Hertz theories, elastic modulus was obtained with nanometer-scale resolution. Furthermore, sample deformation by the force exerted was also estimated from the force curve analyses. When PS/PIB blend samples were observed in contact-mode operation, PIB rich phases appeared as depressions. However, this was artifact caused by very small elastic modulus of PIB. We reconstructed "real height image" from original height image and sample deformation image, which was almost flat at the apparent depression. We will report its detailed procedure together with the method of obtaining elastic modulus distribution image at the site.
