FIXING MEMBER

摘要

A fixing member used for fixing a toner image on a recording material includes: a base layer; and a porous elastic layer provided on the base layer and containing a needle-like filler. The elastic layer has a thermal conductivity with respect to a longitudinal direction thereof in a first region where the elastic layer is contactable to the recording material on the fixing member, and the thermal conductivity is 6 times to 900 times a thermal conductivity with respect to a thickness direction in the first region. The elastic layer has a thermal conductivity with respect to the thickness direction thereof in a second region outside the first region with respect to the longitudinal direction, and the thermal conductivity with respect to the thickness direction in the second region is larger than the thermal conductivity with respect to the thickness direction in the first region.

1. A fixing member used for fixing a toner image on a recording material, comprising:
a base layer; and a porous elastic layer provided on said base layer and configured to contain a needle-like filler, wherein said elastic layer has a thermal conductivity with respect to a longitudinal direction thereof in a first region where said elastic layer is contactable to the recording material on said fixing member, the thermal conductivity is 6 times to 900 times a thermal conductivity with respect to a thickness direction in the first region, and wherein said elastic layer has a thermal conductivity with respect to the thickness direction thereof in a second region outside the first region of said fixing member with respect to the longitudinal direction, the thermal conductivity with respect to the thickness direction in the second region is larger than the thermal conductivity with respect to the thickness direction in the first region.
