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： A fixing device includes an endless flexible belt, a stationary pad, a rotary pressure member, and a lubrication mechanism. The endless flexible belt is looped into a generally cylindrical configuration extending in an axial direction thereof for rotation in a rotational, circumferential direction thereof. The stationary pad is stationarily disposed inside the loop of the belt. The rotary pressure member is disposed parallel to the belt. The rotary pressure member presses against the stationary pad via the belt to form a nip therebetween, through which a recording medium is conveyed in a conveyance direction. The lubrication mechanism supplies lubricant between the stationary pad and the belt, and includes a first sheet of lubricant-impregnated material and a second sheet of lubricant-impregnated material.

摘要： An image forming apparatus includes a fixing device including a fixing rotary body and a heater for heating the fixing rotary body. An opposed body contacts the fixing rotary body with releasable pressure therebetween to form a fixing nip therebetween through which a recording medium is conveyed. A heat shield is interposed between the heater and the fixing rotary body and movable in a circumferential direction of the fixing rotary body to shield the fixing rotary body from the heater in a variable circumferential direct heating span of the fixing rotary body where the heater is disposed opposite the fixing rotary body directly. A controller halts the heat shield instantly when a fault occurs during a print job.

摘要： Heat-equalizing rotation of a fixing member and a pressing member for equalizing the distribution of the temperature of a surface of the fixing member in a width direction is performed after a recording medium having a size less than or equal to a predetermined size in the width direction passes a nip portion and before a recording medium having a size greater than the predetermined size in the width direction passes the nip portion. Further, a termination condition of the heat-equalizing rotation is selected from among a plurality of different kinds of termination conditions, based on image formation related information related to next image formation performed after the heat-equalizing rotation.
