ABSTRACT:
A roll useful in fusing marking material to a print sheet includes a coating disposed on at least a portion of the inner surface thereof. A lamp disposed inside the roll supplies radiant energy to the inner surface. The coating changes its absorptivity (such as color) as desired, to obtain specific desired temperatures at different portions of the roll. The coating can be thermochromic, changing its absorptivity in response to local temperature; or electrochromic, changing its absorptivity in response to an external electrical stimulus.
