Abstract PROBLEM TO BE SOLVED: To provide a rotating body for pressure application that suppresses the temperature rise at a non-paper feed part and reduces the start-up time, a manufacturing method of the same, and a heating device that includes the rotating body for pressure application.SOLUTION: There is provided a rotating body for pressure application used in a heat fixing device and including a base and an elastic layer formed on the base and having pores, where the elastic layer includes an acicular filler, and in the acicular filler, the thermal conductivity λ1 of the elastic layer in a direction along the rotation shaft of the rotating body for pressure application is six times or more and 900 times or less the thermal conductivity λ2 of the elastic layer in the thickness direction. 【課題】非通紙部昇温を抑制しつつ、立ち上がり時間の短縮を実現する加圧用回転体及びその製造方法、ならびに該加圧用回転体を具備する加熱装置を提供すること。【解決手段】熱定着装置に用いられる加圧用回転体であって、基体と、該基体の上に形成された、空隙を有する弾性層とを有し、該弾性層は、針状フィラーを含み、該針状フィラーは、該弾性層の該加圧用回転体の回転軸に沿う方向の熱伝導率λ1が、該弾性層の厚み方向の熱伝導率λ2の6倍以上、900倍以下であることを特徴とする加圧用回転体。【選択図】図5A
