Abstract

In electrostatographic fusing apparatus with radiant type fusers it frequently happens that the copy sheets with the toner image thereon end up being attached, stuck to or fused to the surface of the fuser reflectors. W e propose to provide radiant fuser surfaces which have a textured pattern such as that illustrated in the figure, which may be formed by coining, embossing, stamping or otherwise dimpling the surface to minimize drag and contamination. In addition, the Chevron pattern indicated in the figure provides minimum heat area contact between the paper and the fuser reflector surface. It has the additional advantage of permitting duplexing of copies for the fabrication of the lower reflector. The result may be achieved merely by the wrapping of a platinum wire, for example, in the form of a Chevron pattern around the fuser reflector. Alternatively, a highly reflective aluminum sheet may be coined to produce ridges, for example, .007" high by .015" wide in the direction of the paper path Chevron pattern. Alternatively, glass may be roll formed to achieve the Chevron pattern which can be placed on top of a diamond turned fuser reflector. These proposals offer the opportunity of being able to reduce, if not eliminate, the need for relatively expensive gold plating reflecting surfaces in radiant fusers.
