We find a remarkable transition of the frictional-force microscopy image pattern of a graphite surface depending on the load. This transition is observed in both simulations and experiments. Based on the Tomlinson mechanism, the image transition can be explained as the change of the size and shape of the stable region of the cantilever basal position.
