The fiber of the present invention is excellent in magnetic field responsiveness and conductivity, including a polymer having a fiber forming ability, containing a spherical magnetic material having a saturation magnetic flux density of 0.5 Tesla or more. In a preferred embodiment, the average particle diameter of the (a) spherical magnetic material is 5 µm or less, (b) the holding force of the spherical magnetic material is 1000 A / m or less, and (c) the fiber contains 20 to 90% by weight of the spherical magnetic material. It is a composite fiber containing a magnetic layer and the protective layer whose content of spherical magnetic material is less than 20 weight%.n n n BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to fabrics such as woven fabrics using such fibers, short fibers, brush rollers containing the same, and electrophotographic apparatuses using the brush rollers.n n n Fiber, Textile, Knit, Fabric, Short Fiber, Brush Roller, Magnetic Responsiveness, Conductive |
