Abstract (en)

To provide the melt-extrudable material suitable for forming a transfer layer of photosensitive part of image forming device, particularly the melt-extrudable material comprising a fluorine-containing resin which is excellent in non-sticking property, smoothness and strength and is easy in controlling of volume resistivity, and a transfer belt produced by using the melt-extrudable material. The melt-extrudable material is suitable for forming a transfer layer of photosensitive part of image forming device and comprises a composition comprising (A) a filler and (B) a fluorine-containing thermoplastic resin; at least a part of the filler being fluorinated and the composition giving a coating film having a surface volume resistivity of from 10<8> to 10<13> OMEGA .cm, a water contact angle of not less than 96 degrees, a surface roughness Ra of not more than 0.5 mu m and a tensile strength of not less than 400 kgf/cm<2> at 25 DEG C.
