20140105659 | HEATING BELT - A heating belt has a sliding layer on an inner surface of a base member, the sliding layer composed of a polyimide resin layer formed by mixing a first polyimide precursor and a second polyimide precursor whose loss elastic modulus is greater than that of the first polyimide precursor. A high wear resistance and a high stick-slip inhibition effect can be retained for the sliding layer because the first polyimide precursor and the second polyimide precursor are mixed. | 04-17-2014 |
20140116599 | FIXING MEMBER MANUFACTURING METHOD - A fixing member manufacturing method includes: a step of forming a laser-irradiated region by irradiating a surface of an elastic material with laser light of 120 nm or more and 10600 nm or less in oscillation wavelength; a step of applying an adhesive onto the elastic material on which the laser-irradiated region is formed; a step of coating the elastic material, after the applying step, with a resin tube and then elongating the resin tube on the elastic material in a longitudinal direction; a step of locally fixing the elastic material and the resin tube while maintaining the elongation of the resin tube in the longitudinal direction by heating the laser-irradiated region from above the resin tube; and a step of fixing a whole of the resin tube to the elastic material by curing the adhesive. | 05-01-2014 |
20140116603 | FIXING MEMBER MANUFACTURING METHOD AND FIXING MEMBER MANUFACTURING APPARATUS - A fixing member manufacturing method includes: a step of holding a longitudinal end of a resin tube by a first holding tool; a step of holding another longitudinal end of the resin tube by a second holding tool; a step of decreasing a distance between the first and second holding tools each holding the resin tube, by a predetermined amount; a step of expanding, after the decreasing step, the resin tube in a radial direction; and a step of externally fitting the resin tube, expanded in the radial direction, around an elastic material coated with an adhesive. | 05-01-2014 |
20140116611 | FIXING MEMBER MANUFACTURING METHOD AND FIXING MEMBER MANUFACTURING APPARATUS - A fixing member manufacturing method includes: a step of coating an outer peripheral surface of an elastic material with an adhesive; a step of externally fitting a resin tube around the elastic material coated with the adhesive; a step of temporarily fixing the resin tube onto the elastic material by heating the resin tube at a longitudinal end portion; a step of temporarily fixing the resin tube onto the elastic material by heating the resin tube at the other longitudinal end portion except for a circumferential part of the resin tube; a step of squeezing out an excessive adhesive from between the elastic material and the resin tube, in a direction from the longitudinal end portion to the other longitudinal end portion of the resin tube; and a step of fixing the resin tube onto the elastic material by heating the adhesive. | 05-01-2014 |
20140116612 | FIXING MEMBER MANUFACTURING METHOD AND FIXING MEMBER MANUFACTURING APPARATUS - A fixing member manufacturing method includes: a first step of externally fitting a resin tube around an elastic material; and a second step of squeezing an excessive adhesive between the elastic material and the resin tube. The second step includes: a step of externally fitting, around the resin tube in a longitudinal end side, a ring member having an inner diameter larger than an outer diameter of the resin tube externally fitted around the elastic material; and a step of moving the ring member from the longitudinal end side toward another longitudinal end side of the resin tube while bringing the ring member into contact with an outer peripheral surface of the resin tube by air pressure. | 05-01-2014 |
20140119789 | FIXING MEMBER AND MANUFACTURING METHOD THEREOF - A fixing member includes an elastic layer and a toner parting layer. The elastic layer includes a laser-irradiated region formed by being irradiated at longitudinal end portions of the elastic layer with laser light except for at least one non-laser-irradiated region with respect to a circumferential direction of the elastic layer. The elastic layer is coated with the toner parting layer. | 05-01-2014 |
