Abstract: A thermally conductive pipe includes a pipe of which both end portions are closed, a working liquid that is sealed inside the pipe and vaporizes and liquefies, and a liquid transfer unit that exists along a longitudinal direction inside the pipe and transfers the liquefied working liquid at least in the longitudinal direction, in which the liquid transfer unit has, in a case of being viewed in a cross section of the pipe, which is orthogonal to the longitudinal direction, a first liquid transfer unit that is in contact with at least a partial range of an inner wall surface of the pipe and a second liquid transfer unit that is not in contact with the inner wall surface of the pipe and the first liquid transfer unit.

Abstract: A fixing device includes a rotatable endless belt; a planar heat-generating section in which at least a downstream end portion in a movement direction of the belt is in pressure contact with a rotating body via a pressure contact portion and a cross-sectional shape of a downstream edge portion being in contact with an inner surface of the belt is formed in a curved shape having a curvature radius of 0.01 mm or more 0.2 mm or less or in a shape in which the edge portion is cut out over the dimension; and a holding section that is disposed inside the belt and holds the planar heat-generating section to be in pressure contact with the rotating body.

Abstract: A thermally conductive pipe includes a pipe having closed both end portions; a working fluid that is enclosed in inside of the pipe and that is vaporized and liquefied; and a liquid transfer member that extends in a longitudinal direction of the inside of the pipe and that transfers the liquefied working fluid at least in the longitudinal direction. An occupancy rate of a cross-sectional area of the liquid transfer member to a cross-sectional area in a transverse direction of the inside of the pipe is in a range of 20% or more and 50% or less.

Abstract: A heating device includes: a heater including plural heating portions that generate different amounts of heat in a width direction that crosses a transport direction in which a heating object is transported; and plural temperature equalization members that are disposed on the heater and extend in the width direction with an interval provided therebetween in the transport direction, the plural temperature equalization members equalizing a temperature of the heater in the width direction. One of the plural temperature equalization members has a length greater than or equal to a width of a maximum passing region of the heater through which the heating object passes when the heating object has a maximum width. A remaining one of the plural temperature equalization members has a length less than the length of the one of the plural temperature equalization members.

Abstract: A fixing device includes a movable belt; and a planar heat-generating section that is in contact with the belt and in which, among plural heat-generating portions provided in a movement direction of the belt, a heat-generating portion on an upstream side in the movement direction of the belt has a larger heat generation amount than a heat-generating portion on a downstream side.

Abstract: A heat pipe includes a tubular member that is a hollow member in which liquid is encapsulated and of which an inner surface is subjected to an oxidation treatment in advance and a movement section that moves the liquid encapsulated and liquefied in the tubular member along a longitudinal direction of the tubular member by means of a capillary phenomenon and of which a surface is subjected to an oxidation treatment in advance.
