Abstract

A fuser member has a composite layer including (1) a first layer of a first material which is an elastomer; (2) a second layer of a second material comprising elastomeric fluoropolymer which is a crosslinked polymer having repeating units of tetrafluoroethylene and perfluoroalkyl perfluorovinylether; and (3) a layer intermediate to and continuous with the first and second layers in which the proportion of the first material to the second material gradually varies from substantially only the first material to substantially only the second material. Methods of making the fuser member by a spray technique and of using the fuser member to fuse toner images to a receiver are also disclosed.
