置。 A fixing device that includes a heating roll and a pressure roll that rotate while being pressed against each other, and fixes the unfixed toner image by inserting a sheet of paper on which an unfixed toner image is formed between these rolls. A supply roll that rotates in pressure contact with the surface of the pressure roll and holds a liquid mold release agent inside is detachably arranged on one side of the pressure roll. The mold release agent was formed so as to be intermittently pressed against the surface of the heating roll or pressure roll to apply a mold release agent to the surface of the heating roll when the roll and the pressure roll are being inserted or not being inserted. A fixing device characterized by:
