<p>A roller for a fixing device which is equipped with a sponge layer having a large number of through-holes bored in parallel with the longitudinal direction of the shaft at predetermined intervals along its circumferential direction, or a through-hole bored helically in the longitudinal direction of the shaft, and deposited on the circumferential surface of the shaft, and with a surface coating layer applied to the circumferential surface of the sponge layer. Another roller for a fixing device which is equipped with a sponge layer having a large number of through-holes bored in prallel with the longitudinal direction of the shaft at predetermined intervals along its circumferential direction, or a through-hole bored helically in the longitudinal direction of the shaft, and deposited on the circumferential surface of the shaft; and a 20 to 150 νm-thick surface coating layer made of a fluororesin and applied to the circumferential surface of the sponge layer through an adhesive layer, wherein at least one of the sponge layer, the adhesive layer and the surface coating layer has a volume resistivity of not greater than 109 Φ.cm.</p> |
