Abstract
A fixing device slide member has a surface 40a of a sheet body 40, which surface is made of heat-resistant resin. A specific wear rate on the surface 40a of the sheet body 40 in the ring-on-disc test is 10×10−8 mm3/(N×m) or less on condition that a counterpart material is aluminum, roughness Ra is equal to 0.2 micrometer, PV is equal to 51.2 MPa×m/min, and measuring time is 50 hours. Thus, the surface 40a of the sheet body 40 is enhanced in wear resistance so as to be free from generation of worn powder, which suppresses torque increase in a pressurizing belt caused by the worn powder.
Claims17
A fixing device slide member, comprising
- a sheet body of the fixing device, having a first layer, a substrate formed out of a glass cloth on the first layer and a second layer on the substrate, wherein one surface of the sheet body is made of a material containing heat-resistant resin, wherein
- a specific wear rate of the one surface of the sheet body in a ring-on-disc test is 10×10−8 mm3/(N×·m) or less on condition that a counterpart material is aluminum, roughness Ra is equal to 0.2 micrometer, pressure×velocity (PV) is equal to 51.2 MPa×m/min, and measuring time is 50 hours, and wherein there is no generation of worn powder from the sheet body when the fixing device slide member is used in a fixing device.
A fixing device, comprising:
- a pair of rotation units which rotate in a state of being in contact with each other;
- a pressing member which is placed inside one rotation unit out of the pair of the rotation units for pressing an inner surface of the one rotation unit toward the other rotation unit out of the pair of the rotation units;
- and
- a fixing device slide member of the fixing device, having a sheet body with a first layer, a substrate formed out of a glass cloth on the first layer and a second layer on the substrate, wherein, one surface of the sheet body is made of a material containing heat-resistant resin, wherein
- a specific wear rate of the one surface of the sheet body in a ring-on-disc test is 10×10−8 mm3/(N×·M) or less on condition that a counterpart material is aluminum, roughness Ra is equal to 0.2 micrometer, pressure×velocity (PV) is equal to 51.2 MPa×m/min, and measuring time is 50 hours, the fixing device slide member being placed between the one rotation unit and the pressing member, wherein
- the one surface of the sheet body of the fixing device slide member is made to slide on the inner surface of the one rotating rotation unit, and wherein there is no generation of worn powder from the sheet body when the fixing device slide member is used in the fixing device.
