PRESSURE ROTATING MEMBER, METHOD FOR MANUFACTURING THE SAME, AND HEATING DEVICE

摘要

The present invention relates to a pressure rotating member which achieves the shortening of a warm-up time while suppressing a non-recording material-contacting area's temperature rise. The pressure rotating member which is used in a thermal fixing apparatus includes: a substrate; and an elastic layer that is formed on the substrate and has a void, wherein the elastic layer contains a needle-shaped filler, wherein the needle-shaped filler has such a thermal conductivity λ1 of the elastic layer in a direction along a rotary axis of the pressure rotating member as to be 6 times or more and 900 times or less of a thermal conductivity λ2 of the elastic layer in a thickness direction.
