    The two-dimensional electron gas (2DEG) in the quantum Hall regime close to integer filling factors was studied. In a smooth potential gradient, low-compressibility strips corresponding to integer Landau level filling factors are observed. These strips turn out to be significantly wider than predicted by theory, which does not include the disorder potential. The width of the strip is determined by a low, but finite density of states between the Landau levels.
