ABSTRACT:
A fixing device for fixing an unfixed toner image by heating and pressurizing a recording material by which the unfixed toner image is carried includes a heating member having a heat source, a pressurizing member that faces the heating member and that forms a fixing nip region between the heating member and the pressuring member, a belt member that circulates while being tensioned around the heating member and is able to transport the recording material while in contact with a surface of the unfixed toner image of the recording material, and a belt driving device that temporarily stops or decelerates the belt member after a rear edge of the recording material passes through the fixing nip region, and that restores the belt member before a leading edge of a subsequent recording material reaches the fixing nip region.
