摘要： A fixing device includes a heat source; a fixing member looped into a generally cylindrical shape to rotate in a circumferential direction thereof and partially heated by the heat source and to heat a surface of a recording medium bearing an unfixed toner image to fix the unfixed toner image thereon in a fixing process; a rotary pressing member disposed facing the fixing member to form a nip therebetween, through which the recording medium is transported in a transport direction; and a rotation driver to rotate one of the fixing member and the pressing member. In a case in which the fixing member is halted for a reason other than the fixing process while power of the fixing device is on, electric power is not supplied to the heat source and the fixing member is rotated by a predetermined amount or more after the fixing member is halted.

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.
