The potency to be written via ink during recording so as to write the ink image and the re-transferability during re-transferring of the ink image on a recording medium should be retained, securely, for a long term. The transferring layers of the intermediate transferring medium comprise surface layer and intermediate layer, wherein the material of the surface layer comprises a silicone rubber containing 1 to 20 parts by weight of a non-reactive organopolysiloxane of a viscosity of 100 to 100,000 at 25.degree. C. per 100 parts by weight of an addition-type silicone rubber with no inorganic filler; and the material of the intermediate layer comprises a silicone rubber containing 1 to 20 parts by weight of a non-reactive organopolysiloxane of a viscosity of 100 to 100,000 at 25.degree. C. per 100 parts by weight of an addition-type silicone rubber.

A fixing belt is prepared by forming a layer of fluorosilicone rubber or fluorocarbonsiloxane rubber on the outer surface of an endless belt body. The fixing belt shows good toner release and minimal swell with silicone oil and is thus helpful in producing electrophotographic images of quality.

A fuser roll having a metal core shaft has a resilient layer placed around the metal core shaft with at least the surface layer of the resilient layer comprising a fluorosilicone rubber layer containing 5 to 50 wt. % polytetrafluoroethylene. Since this fuser roll is excellent in releasability and silicone oil resistance, the durability is excellent, and the image obtained by a copying machine wherein the roll is used becomes sharp.

There is provided a novel organosilicon compound, 1,3-bis(p-hydroxybenzyl)-1,1,3,3-tetramethyldisiloxane. It is prepared by silylating 1,3-bis(p-methoxybenzyl)-1,1,3,3-tetramethyldisiloxane with trimethylsilyl iodide, followed by desilylation.
