  • Patent number: 6045904
    Abstract: The present invention discloses an image recording member in which a layer containing a setting type silicone resin having a Knoop hardness number of from 1 to 145 on the surface of a substrate made of paper, plastics or the like. Furthermore, this invention discloses a method for recycling an image recording member comprising the steps of contacting the image recording member with the outermost surface of an image releasing member, the outermost layer being formed from a pressure-sensitive adhesive or the like such as hot-melt silicone resin, heating these material and member to transfer a toner from the image recording member to the image releasing member, and separating the image recording member from the image releasing member. Thus, the invention can maintain good fixing of an image forming material with respect to the image recording member, while the image forming material can be removed from the image recording member without damaging the recording surface.
