ABSTRACT:
An image fixing roller includes an exothermic phase transition layer which performs a plurality of phase transitions repeatedly from an amorphous state to a crystalline state. The exothermic phase transition layer may include a plurality of exothermic phase transition materials, or a plurality of exothermic phase transition component layers, each of which exothermic phase transition material or component layer has a different crystallization initiation temperature (Tci), a different exothermic peak temperature (Tcp) and a melting point temperature which is higher than that of a toner fixing temperature. An image fixing apparatus using the above-mentioned image fixing roller and a method of fixing toner images on an image receiving material, using the image fixing roller are proposed.
