involves cascading the developer composition across the electrostatic charge pattern while another technique involves applying toner particles from a magnetic brush this latter technique involves the use of a magnetically attractable carrier vehicle in forming the developer composition after imagewise deposition of the toner particles the image can be fixed e g by heating the toner to cause it to fuse to the substrate carrying the toner if desired the unfused image can be transferred to a receiver such as a blank sheet of copy paper and then fused to form a permanent image the following examples are presented to further illustrate some preferred embodiments of the salts of the invention and to compare their properties and performance to those of salts outside the scope of the invention benzyldimethyloctadecylammonium chloride monohydrate from onyxz chemcial co 100 0 g 0 226 mole was dissolved in hot water 1 5 l and a solution of sodium 3 nitrobenzenesulfonate 56 1 g 0 249 mole 1 10 eq in warm water 1 5 l was added by pouring through a glass funnel which was lightly plugged with glass wool to remove insoluble debris the product immediatly separated as an oil which soon solidified as fine off white crystals the mixture was allowed to cool to room temperature and the precipitate was collected on a medium glass frit 10 20 micron pore size using vacuum the solid was sucked nearly dry and was then recrystallized from toluene ca 10 ml g the crystals were collected on a medium glass frit washed with cold toluene and then with ethyl ether and dried in a vacuum oven 70 u00b0 c the product benzyldimethyloctadecylammonium.
