Abstract: A fixing device includes a fixing belt, a pressuring member, a pressing member, a heat source and a heat transmitting member. The fixing belt is arranged rotatably. The pressuring member is arranged rotatably to come into pressure contact with the fixing belt so as to form a fixing nip. The pressing member presses the fixing belt to a side of the pressuring member. The heat source is arranged at the inside in a radial direction of the fixing belt to radiate a radiant heat. The heat transmitting member comes into contact with an inner circumference face of the fixing belt to absorb the radiant heat radiated from the heat source. A part of the heat transmitting member is sandwiched between the fixing belt and the pressing member.

Abstract: A fixing device includes a fixing belt, a pressure rotating body, a nip member, a heating member, a rotating member and a biasing member. The fixing belt is arranged rotatably around a rotating axis. The pressure rotating body is rotatably arranged at an external diameter side of the fixing belt to come into pressure contact with the fixing belt and to form a fixing nip. The nip member is arranged at an internal diameter side of the fixing belt to press the fixing belt toward a side of the pressure rotating body. The heating member comes into contact with a contacted area in an inner circumference face of the fixing belt to heat the fixing belt. The rotating member sandwiches an end part of the fixing belt with the heating member and is rotated together with the fixing belt. The biasing member presses the heating member to the contacted area.

Abstract: A fixing device includes a fixing belt, a pressure rotating body, a nip member, a supporting member, a heating source, a heat conducting member and a reflecting member. The pressure rotating body is rotatably arranged outside the fixing belt to come into pressure contact with the fixing belt to form a fixing nip. The nip member is arranged inside the fixing belt to press the fixing belt toward the pressure rotating body. The supporting member supports the nip member. The heating source is arranged inside the fixing belt to emit radiant heat. The heat conducting member is supported by the supporting member in a cantilevered state to come into contact with an inner circumference face of the fixing belt and to absorb the radiant heat. The reflecting member reflects the radiant heat toward the heat conducting member and at least partially comes into contact with the heat conducting member.

Abstract: A developing device includes a storing portion, a stirring member, a developing roller, a shield plate, and a guide portion. The storing portion stores developer. The stirring member is rotatably provided in the storing portion and stirs the developer in the storing portion by being rotationally driven in a predetermined first rotation direction. The developing roller is rotatably provided above the stirring member, has a magnet that attracts the developer in the storing portion by a magnetic force, and is rotationally driven in a predetermined second rotation direction. The shield plate is made of a nonmagnetic material and provided at a facing position where the developing roller and the stirring member face each other. The guide portion is provided more on an upstream side in the first rotation direction than the facing position, and guides the developer from the storing portion to the developing roller side.
