摘要:
In a method for evaluating a fixing member to fix a toner having a surface layer, a hardness test is carried out by applying a pressure deformation from the surface side of the fixing member, and when a deformation of the surface layer by the pressure deformation is within an elastic range, the fixing member is regarded as a standard product.

In a fixing member having an elastic layer of heat resistance rubber provided on a substrate and a separation layer of fluorocarbon resin provided on the elastic layer, the fluorocarbon resin is that a tensile strength of a 30 μm coating film burned at 340° C. is equal or greater than 25 MPa. The heat resistance rubber includes, for example, silicone rubber or fluorosilicone rubber as a major component. The fluorocarbon resin includes PFA as a major component, for example.

An image forming apparatus includes a fixing unit for fixing a toner image on a recording sheet. The fixing unit includes a fixing belt, a support roller, and a coil. The fixing belt rotates and applies heat on the recording sheet to fix the toner image on the recording sheet. The support roller rotates and supports the fixing belt. The coil has a loop-like or U-like shape and generates a magnetic flux to induce heat in the fixing belt and the support roller. The coil sandwiches the support roller and the fixing belt in a manner that the coil faces an outer circumferential surface of the support roller via the fixing belt and an inner circumferential surface of the support roller. The above configuration of the coil controls a surface temperature of the fixing belt.

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.
