1. An information processing apparatus, which simulates a behavior of a sheet-like printing medium having a flexibility when the printing medium is conveyed in a conveying path including a convey roller pair, comprising:
setting means for setting a condition including an information associated with a rigidity of the convey roller pair that consist of a first roller and a second roller arranged in the conveying path;
contact area shape formation means for forming a shape along a surface shape of the first roller having a higher rigidity than the second roller as a shape of a contact area where the first roller and a second roller contact each other when a rigidity ratio of the first roller to the second roller based on the condition set by said setting means is not less than a predetermined value; and
simulation means for simulating the behavior of the printing medium when the printing medium is conveyed in the conveying path on the basis of the shape of the contact area.
