摘要： A nip former that forms a nip between an endless belt and a pressure rotator includes a base that is made of aluminum and has a nip forming face disposed opposite the nip. An anodic oxidation coating is treated with sealing and coats at least the nip forming face. The anodic oxidation coating has a thickness that is not smaller than 22 μm and is not greater than 45 μm and a variation in thickness that is not greater than 20 percent. The base and the anodic oxidation coating define a nip forming portion that is disposed opposite the nip. The nip forming portion has a thickness that is not smaller than 0.40 mm and is not greater than 1.20 mm.

摘要： A nip formation pad includes a base, a high thermal conduction member, and an attachment. The high thermal conduction member has a thermal conductivity greater than a thermal conductivity of the base. The attachment is attached to the high thermal conduction member by elastic deformation of the attachment on the base held between the high thermal conduction member and the attachment.

摘要： A fixing device includes a fixing rotator to fix an unfixed image on a recording medium, a pressure member disposed opposite the fixing rotator to press an outer circumferential surface of the fixing rotator; a heating source disposed inside an inner circumferential surface of the fixing rotator to heat the fixing rotator, and a composite member disposed inside the inner circumferential surface. The composite member includes a first member, a second member attached to the first member, and an inspection region for measurement of glossiness. The first member and the second member have a difference in glossiness. The inspection region allows identification of which one of the first member and the second member is present on a surface of the inspection region based on the glossiness of the inspection region, and determination of that the fixing device has a desired fixing configuration based on a result of the identification.

摘要： The viscosity of a puncture-preventing sealant (7) is set in a range of 25 to 35 dPa·s, and a thixotropy index is set in a range of 6.5 to 11.0, the sealant (7) being filled in a sealant chamber (6) defined to extend along an outer periphery of an air chamber (5) in a tire (T). When the tire (T) is being rotated by traveling of a vehicle, the viscosity of the sealant (7) is reduced by a stirring action provided by a vibration or a centrifugal force of the sealant (7), whereby the sealant (7) can be diffused uniformly in the sealant chamber (6). When the vehicle has been stopped and the stirring action has been extinguished, the viscosity of the sealant (7) is increased, whereby the sealant (7) is maintained in a state in which it has been diffused uniformly in the sealant chamber (6) without flowing downwards in the sealant chamber (6) by gravitation. Therefore, even when the vehicle is travelling at a high speed, the generation of a vibration and a noise can be prevented. In this manner, the puncture-preventing sealant is provided, which has such a nature that the sealant is easy to flow due to a low viscosity during traveling of a vehicle, and the sealant is difficult to flow due to a high viscosity when the sealant is left to stand.

摘要： An image heating apparatus for heating a toner image in a nip while conveying a recording material on which the toner image is held is provided. The image heating apparatus includes: a heater configured to generate heat by being supplied with electric power from an AC power source; a rotatable heating member configured to be heated by the heater; a pressing member configured to form the nip in contact to the rotatable heating member; a temperature detecting portion configured to detect a temperature of the heater or the rotatable heating member; and a controller configured to set the electric power supplied to the heater every renewal cycle depending on a detected temperature by the temperature detecting portion. The renewal cycle is shorter in a rise period of the heater than in a period in which the recording material is conveyed in the nip.
