Abstract
1,172,839. Xerographic developers. RANK XEROX Ltd. Nov.29, 1966 [Dec. 2, 1965], No.53505/66. Heading G2H. A xerographic cascade developer comprises 1 part by weight of toner particles, 10-200 parts of non-magnetic carrier particles, and 0À02-20 wt.% based on the toner of at least one solid, stable hydrophobic metal salt of a fatty acid at or immediately adjacent external surfaces of the toner and/or carrier particles. The salt may be loosely mixed with, or dispersed throughout the particles, or milled into their surfaces. Suitable toner particles consist of styrene/n-butyl methacrylate copolymer, polyvinyl butyral and carbon black, and suitable carriers are NaCl, NH 4 Cl, Al KCl 4 , SiO 2 Rochelle salt, NaNO 3 , Al(NO 3 ) 3 , KClO 4 , Zr, Si, polymethyl-methacrylate, glass and sand.
