ABSTRACT:
A pressure roller forms a nip for contacting a heating member to pinch and convey a heat recording material. The roller includes a core metal and an elastic layer containing filler. The elastic layer containing the filler includes thermal conductive filler with a length of not less than 0.05 mm and not more than 1 mm and with a thermal conductivity λfin the longitudinal direction in a range of λf≧500 W/(m·k), being dispersed in not less than 5 vol % and not more than 40 vol %. The elastic layer containing the filler has a thermal conductivity λyin the longitudinal direction perpendicular to a recording material conveyance direction, of λy≧2.5 W/(m·k) and an ASKER-C hardness of the filler is not more than 60 degrees. A solid rubber elastic layer with a thermal conductivity λ in a thickness direction of not less than 0.16 W/(m·k) and not more than 0.40 W/(m·k) is included.
