A fixing member for use in a fixing assembly of an image-forming apparatus of an electrophotographic or electrostatic recording system has a conductive layer and a releasing layer formed on the conductive layer. In the releasing layer, any one or both of medium-resistance particles and medium-resistance whiskers are dispersed, and the releasing layer has a surface resistivity of 1.0.times.10.sup.8 .OMEGA. or below and a volume resistivity of 1.0.times.10.sup.8 .OMEGA.cm or above. The fixing assembly having such a fixing member may be provided in an image-forming apparatus having the fixing assembly, and the fixing member has a superior anti-offset properties and proofness to smeared image trailing edges.
