Abstract
When filler particles are added to a surface layer of a fixing member in order to enhance a toner releasing property, if the filler particles are randomly oriented, chemical affinity between the surface layer of the fixing member and toner is enhanced and a sufficient effect cannot be accomplished. Therefore, whisker-shaped filler particles are added to the surface layer of the fixing member, and the filler particles are oriented to approximately follow a rotation direction of the fixing member.
Claims15
A fixing member comprising
- a base layer;
- and
- a surface layer provided on the base layer,
- wherein filler particles are added to the surface layer and 75% or more of the filler particles have an aspect ratio of 5 or more and are oriented to be within ±30° with respect to a rotation direction of the fixing member.
1 more element
A fixing device comprising
- a fixing member including a base layer and a surface layer provided on the base layer and configured to fix a toner image formed on a sheet;
- and
- a heater configured to heat the fixing member,
- wherein filler particles are added to the surface layer and 75% or more of the filler particles have an aspect ratio of 5 or more and are oriented to be within ±30° with respect to a rotation direction of the fixing member.
1 more element
A method of producing a fixing member comprising:
- adding filler particles having an aspect ratio of 5 or more to fluorine-based resin that is a base of the fixing member;
- and
- coating the resin to which the filler particles are added onto a base layer while the base layer configuring the fixing member is rotated.
