A method for forming a roll core for use in an electrophotographic image forming device according to one example embodiment includes shaping the roll core from a mixture of an uncured elastomer and hollow microparticles. The elastomer of the shaped roll core is cured without permanently expanding hollow microparticles positioned near the outer surface of the shaped roll core. After curing, the hollow microparticles positioned near the outer surface of the shaped roll core are permanently expanded to form the roll core having compressible and resiliently recoverable hollow microparticles extending beyond an outer circumference of the roll core and providing a surface texture to the roll core.
