続的に除電できると考えられる。The inventor of the present invention uses the electronic conjugate to prevent excessive current from leaking and damaging the photosensitive drum even if the fibers of the static elimination sheet fall off and adhere to the photosensitive drum of a copying machine or the like. As a result of continued research on the static elimination sheet made of non-woven fabric coated with a polymer, it was found that the static elimination performance of this static elimination sheet causes the fiber coated with the electron-conjugated polymer to be oxidized and deteriorated to reduce the static elimination performance. Focusing attention, the present invention has been completed. That is, the static elimination sheet of the present invention, the one surface of the fiber sheet facing the object to be charged is coated with the electron conjugated polymer, and since the electron conjugated polymer is coated with the conductive substance, the electron conjugated polymer Is in non-contact state with air, oxidative deterioration can be suppressed, and it is considered that even a charged object having a large amount of charge can be continuously discharged.

できる。In the present invention, a fiber sheet such as a non-woven fabric, a woven fabric or a knitted fabric is formed from the above fibers. Among them, the non-woven fabric can be preferably used because the orientation direction of the fibers can be in the thickness direction, the number of fiber ends that can participate in corona discharge increases, and the charge can be easily removed by corona discharge. Such a nonwoven fabric in which the fiber orientation direction is the thickness direction is obtained by, for example, a fiber web obtained by a card method, an air lay method, a wet method, a spun bond method, a melt blow method, or the like in a fluid flow such as water, or a machine such as a needle.

In addition, the friction electrification method and the electrification voltage measurement are based on the JIS standard, L1092 reference method, and the friction electrification voltage tester (Kanebo Engineering Co., Ltd., E
ST-7). In addition, this measurement is performed at a temperature of 20.
It was carried out under conditions of ° C and humidity of 50%. The results are shown in Table 1.
