A rubbing component used in a configuration of a post-processing device together with a transport section that transports a medium, on which an image formed using an imaging material and wax are held and which has passed through a fixing section that fixes the image of the medium by heating and pressurization, at a predetermined speed by nipping the medium,
- the rubbing component being located upstream or downstream of the transport section in a transport direction of the medium and rubbing a surface of the medium such that a layer thickness after passage of the wax held on the surface of the medium is reduced, in a case where the medium transported by the transport section passes through the rubbing component, the rubbing component comprising:
- at least on a surface, a rubbing portion in which fibers are arranged in a regular pattern in a direction intersecting the transport direction of the medium,
- wherein the rubbing portion comes into contact with the surface of the medium with portions of the fibers other than end portions.
