Abstract: A fixing device includes an endless belt member and a rotating body that are arranged to come in pressure contact with each other, the endless belt member and the rotating body having a source of heat generation; a pressing member that is arranged within the endless belt member and comes in pressure contact with the endless belt member to the rotating body; and a lubricant reservoir that is provided in the pressing member and reserves a semisolid or solid state lubricant, wherein a width in a central portion of the lubricant reservoir is wider than that in both ends of the lubricant reservoir, and widths along a length direction of the lubricant reservoir narrows from the central portion toward the both ends.

Abstract: A fixing device comprises a heating roll; an endless belt; and a pressurizing member that forms a pressure contact portion for pushing the endless belt against an outer peripheral surface part of the heating roll from an inner peripheral surface side of the pressurizing member so that a recording medium holding an unfixed image passes between the pressure contact portion and the heating roll, wherein the pressurizing member includes: a hard pressurizing member and a soft pressurizing member the hard pressurizing member, and the soft pressurizing member are disposed in a state in which a clearance is present between the hard pressurizing member and the soft pressurizing member in a specific region part so that at least a specific recording medium passes in a fixing region of the pressure contact portion in the rotating axis direction of the heating roll.

Abstract: A fixing device includes a heating member disposed with an internal heating source and a pressuring member that presses against the heating member. The fixing device is configured to be attachable to and detachable from an image forming apparatus body, and includes: brackets that retain the heating member; pressuring levers that retain the pressuring member and are movably supported in the brackets; urging means that push the pressuring levers in a direction where the pressuring member presses against the heating member; and cams that are rotatably supported in the brackets, contact the pressuring levers, and adjust the pressuring force of the pressuring member.
