摘要： A fixing device includes a fixing belt that is rotatable and a pressure rotator that is pressed against the fixing belt to form a fixing nip therebetween. A polishing roller separably contacts the fixing belt and slides over an outer circumferential surface of the fixing belt while the polishing roller is pressed against the fixing belt. At least one support supports and stretches the fixing belt. A polishing aid, which is disposed opposite the polishing roller via the fixing belt, supports and stretches the fixing belt. The polishing roller is disposed opposite the polishing aid via the fixing belt to form a polishing nip between the polishing roller and the fixing belt while the polishing roller is pressed against the fixing belt. The polishing roller changes a rotation locus of the fixing belt along at least a part of a circumferential face of the polishing roller.

摘要： A fixing device includes a fixing belt being endless and rotatable in a predetermined direction of rotation. The fixing belt includes an inner circumferential face applied with a fluorine compound. A nip formation pad is not rotatable. The inner circumferential face of the fixing belt slides over the nip formation pad. A pressure rotator presses against the nip formation pad via the fixing belt to form a fixing nip between the fixing belt and the pressure rotator. At least one heater heats the fixing belt. The heater includes a glass tube filled with an inert gas containing, as a main ingredient, a substance having a first molecular weight greater than a second molecular weight of argon.

摘要： An image forming apparatus includes a fixing device that includes a heater to heat a fixing rotator, an opposed rotator to press against the fixing rotator to form a fixing nip therebetween, and at least one rotary body to convey a recording medium to the fixing nip. A controller rotates the fixing rotator in a forward direction to fix a toner image on the recording medium. The controller stops the heater and rotates the fixing rotator in a predetermined rotation direction when a failure occurs while the fixing device is activated. The controller determines that the predetermined rotation direction is the forward direction or a backward direction according to the at least one rotary body that sandwiches the recording medium, if the fixing nip and the at least one rotary body sandwich the recording medium simultaneously when the failure occurs while the fixing device is activated.
