  • POLYMER FILM, TUBULAR FIXING MEMBER, FIXING DEVICE, AND IMAGE FORMING APPARATUS
    Publication number: 20240353782
    Abstract: A polymer film includes at least one type of polymer selected from the group consisting of a resin and rubber and fillers dispersed in the polymer; in which in a case where the polymer film is three-dimensionally analyzed with FIB-SEM, a film thickness of the polymer film is denoted by Tm, and a length of the filler in a film thickness direction of the polymer film is denoted by Lf, a proportion of the number of fillers having Lf/Tm of 0.01 or more and less than 1.0 to the number of all the fillers is more than 40% and less than 100%.
