ABSTRACT:
The fusing device using a heat accumulated heating medium and the fusing process using the same is disclosed. The fusing device comprises a heating member having relatively low heat capacity, a heat accumulating system for temporarily accumulating heat energy at the heating member, a nip arrangement for nipping the toner image between the heating member and the copy sheet with an appropriate pressure contact so that the nip arrangement primarily transfers the heat energy from the heating member to the toner image and subsequently cools the toner image, a cooling system for cooling the toner image between the heating member and the copy sheet and a detaching system for detaching the copy sheet from the heating member. The thermal efficiency of the fusing device and process speed for the fusing operation is improved. The fusing condition for both of black color toner image and full color toner image is finely adjustable in this fusing device.
