    摘要： A fixing device includes a rotatable, endless belt, a stationary heater, a stationary pad, a rotatable pressure member, and a heat conductive member. The rotatable, endless belt is looped into a generally cylindrical configuration. The stationary heater is disposed inside the loop of the belt to radiate heat to the belt. The stationary pad is disposed inside the loop of the belt. The rotatable pressure member is disposed parallel to the stationary pad with the belt interposed between the pressure member and the stationary pad. The pressure member presses against the stationary pad via the belt to form a fixing nip therebetween through which a recording medium passes. The heat conductive member is interposed between the belt and the heater to transfer heat radiated from the heater by conduction therethrough to the belt.

    摘要： An image forming device forms a toner image on a recording medium. The recording medium goes through a fixing nip N between a fixing member and a pressure member in a fixing unit where the toner image is fixed on the recording medium. A fixing temperature detector detects the temperature of the fixing member. A fixing temperature control unit controls a heater that heats the fixing member so that the detected temperature becomes a target temperature. A size control unit of white space sets a white space at a tip of the recording medium in a direction of the recording medium movement. When a paper counter counts more than a predetermined paper count, the size control unit increases the size of the white space. The fixing temperature control unit decreases the target fixing temperature when the white space goes through the fixing nip.

    摘要： A fixing device includes a rotary endless fixing belt; a nip forming member disposed in an interior of the fixing belt; a rotary opposed member to contact the nip forming member via the fixing belt to form a nip together with the fixing belt; a heat source to directly heat the fixing belt at a portion other than the nip, including at lease one heat-generation part disposed outside lateral ends of a maximum area of the fixing belt where a recording medium passes through, wherein a recording medium carrying an unfixed image is conveyed to the nip and the fixing device fixes the unfixed image onto the recording medium; and a shielding member disposed between the fixing belt and the heat generation part of the heat source and configured to shield heat from the heat source at least at an area outside the maximum passing area of the recording medium.
