  • Patent number: 8309172
    Abstract: A method and a device for coating a hollow cylindrical member. The method includes radially coating an entire inner surface of the hollow cylindrical member with a first coating material discharged by a first slit nozzle and simultaneously circularly coating an entire outer surface of the hollow cylindrical member with a second coating material discharged in an axial direction of the hollow cylindrical member by a second slit nozzle located opposite the first slit nozzle with the hollow cylindrical member therebetween. The first slit nozzle and the second slit nozzle discharge the first coating material and the second coating material, respectively, to a same height of the hollow cylindrical member relative to the inner surface and the outer surface thereof.

  • Patent number: 7354617
    Abstract: A method for evaluating a fixing belt includes forming a fixing belt which includes a substrate, an elastic layer laminated on the substrate, and a mold releasing layer laminated on the elastic layer. A universal hardness test for the fixing belt is performed. The fixing belt is judged as an acceptable product if a creep value CHU is included within a range of 0.40?CHU ?3.50 (%) when the universal hardness test is performed for the fixing belt and when the creep value CHU, which is measured from the side of the mold releasing layer, is defined by the following formula: CHU=(h2-hl)/hl×100 (%) where h1 is a pushed depth when a test load reaches a predetermined value which is kept for a predetermined period of time, and h2 is a pushed depth when a predetermined period of time is elapsed after the test load is removed.
