  • Patent number: 7120380
    Abstract: An electrostatographic reproduction apparatus includes: a primary imaging member for producing an electrostatic latent image on a receiver, a development station for applying toner particles to the latent image to form a developed toner image on the receiver, a fuser assembly for fixing the developed toner image to form a fused toner image on the receiver, and a transport member for transporting the receiver to or from the fuser assembly. The transport member includes a substrate and an oil-absorbing layer that contains inorganic particles dispersed in an organic binder and is capable of absorbing release oil applied to the receiver bearing the fused toner image.
