Abstract

In an electrophotographic printing machine, a development system deposits toner particles on a latent image recorded on the photoconductive surface. During development, developer material is transported from the storage container to the latent image. A molded plastic storage container holds a supply of developer material therein. The plastic housing may be shaped by either compression molding or injection molding. Preferably, the housing may be made from a synthetic thermoplastic resin such as a polycarbonate. The plastic housing is made from a polycarbonate in an amount of 100 percent by weight. Alternatively, conductive particles such as carbon fibers may be dispersed throughout the polycarbonate resin in the amount of about 5 percent by weight with the polycarbonate resin being about 95 percent by weight. Still another embodiment of the housing may employ a polycarbonate resin of about 95 percent by weight having glass fibers dispersed therein in an amount of about 5 percent by weight. In lieu of polycarbonate, a polyvinylchloride in an amount of about 100 percent by weight may also be used.
