Title:
FIXING BELT AND FIXING DEVICE
Document Type and Number:
Japanese Patent JP2023019044
Kind Code:
A
Abstract:
To provide a fixing belt including an inner face slide layer that can inhibit an increase in torque and stick slip through the duration life.SOLUTION: A fixing belt has at least a cylindrical substrate formed of metal, a slide layer formed on an inner peripheral surface side of the cylindrical substrate, sliding with a backup member, and formed of heat-resistant resin, and a mold release layer formed on an outer peripheral surface side of the cylindrical substrate, and the fixing belt rotates while sliding on its inner surface side with the backup member with the interposition of lubricant and is used for heating and fixing a toner image on a recording material. The slide layer has filler. When a cross section with a thickness direction of the slide layer as a vertical axis is cut out, sections each of which having a length the same as the thickness are provided in an orthogonal direction to the thickness direction, and the area ratio of the filler in each section is converted into a number, and with the average area ratio of the filler in all the sections as Ave%, and the minimum area ratio as Min%, a cycle coefficient A calculated with (Ave%-Min%)÷Ave% satisfies 0.6 or more.SELECTED DRAWING: Figure 6
