A urethane foam-molded article has a base material made of polyurethane foam and composite particles that are included and oriented in the base material. The composite particles have thermally conductive particles that are made of a non-magnetic material and have a thermal conductivity of 200 W/m·K or higher and magnetic particles attached to the surfaces of the thermally conductive particles with a binder and are surface-treated with one or more surfactants selected from a carboxylic acid-type surfactant and a succinic acid-type surfactant.

Provided is a paper feeding roll that prevents paper transportation failures over a long time. A paper feeding rollis provided with an axial bodyand an elastic layerformed on an outer periphery of the axial body. The circumferential surface of the elastic layerhas a plurality of projectionsforming surface unevenness. Each projectionof the plurality of projectionsis shaped such that a position X of a distal-end part preceding in an opposite direction to a paper feeding direction precedes, in the opposite direction to the paper feeding direction, a position Y of a base-end part preceding in the opposite direction to the paper feeding direction.

Paper feeding roll

There is provided a conductive roller for electrophotographic equipment in which a shaft made of core metal has excellent rust resistance. The conductive roller includes a shaft made of core metal, a protective layer formed on the outer periphery of the shaft, and a conductive rubber elastic layer formed on the outer periphery of the protective layer. In a conductive roller for electrophotographic equipment, the conductive rubber elastic layer contains a rubber containing halogen atoms, and the protective layer is formed of a crosslinked material of a composition containing a material obtained by melting and mixing the following components (a) to (c):
