The present invention relates to an image-forming device that comprises a roller
that includes a plurality of micromembers. The micromembers are preferably hook
or loop-like members made of a compliant material such as plastic or rubber. The
micromembers on the roller essentially define a compliant surface, which is self-correcting
for unintentional media thickness variations within a print area. The roller is
rotational such that when the roller contacts the media the rotational or spinning
force is converted to a compressional force, which is sufficient to rupture the
microcapsules in the media.
