However, these conductive fibers have insufficient abrasion resistance and their conductivity is apt to be deteriorated by abrasion, and the conductivity is apt to be deteriorated by heat. Therefore, the conductive fibers are always applied to a high heat portion such as a drum of a copying machine. The static eliminator that is in direct contact has a problem that the conductivity decreases in a relatively short period of time.

Next, the product 1a having the napped portion 5a consisting of the low-conductivity fiber 3 and the high heat-shrinkable fiber 4a having substantially the same fiber length is heat-treated.

In order to cause the high heat shrinkable fiber to shrink more than the low conductive fiber by heat treatment so that the difference in fiber length between the low conductive fiber 3 and the high conductive fiber 4: ΔL falls within the above range, It is essential that the heat shrinkage ratio of the low conductive fiber <the heat shrinkage ratio of the high heat shrinkable fiber, but the difference in the heat shrinkage ratio between the two is 1
It is preferably set to 60%. As the high heat-shrinkable fiber 4a, a fiber having a heat shrinkage ratio higher than that of the low conductive fiber 3 is selected from the materials of the above-mentioned high conductive fiber 4 and used.

For electrostatic flocking, low-conductivity fibers and high-conductivity fibers are mixed together and flocked at the same time, or low-conductivity fibers (or high-conductivity fibers) are first flocked and then high-conductivity fibers are applied. There is a method of implanting the active fibers (or low-conductivity fibers). When the conductive fiber product 1 is manufactured by electrostatically implanting low-conductivity fibers and high-conductivity fibers having different fiber lengths, it is not necessary to use heat-shrinkable fibers as the high-conductivity fibers 4.
The heat treatment may be performed using heat-shrinkable fibers. This method is particularly effective when fibers having a small heat shrinkage rate are used.

mm, nap length 6 mm) was obtained.

Then, the back surface of the base of the tape-shaped product (the surface opposite to the napped portion) was back-coated with an acrylic ester emulsion (manufactured by Dainippon Ink and Chemicals, Inc., trade name: Boncoat, combined with an epoxy hardener).
It was heat-dried at 120 ° C. for 1 minute, and further heat-treated at 140 ° C. for 5 minutes.

The heat treatment causes the highly heat-shrinkable fiber having higher conductivity than the low-conductivity fiber to undergo large heat shrinkage, and as a result,
