Abstract
In an electrographic recording system wherein a dynamic bridge of toner particles, the particles having electrical and magnetic properties, corresponding to a concentrated magnetic field formed between a toner carrier and the recording medium, an improved stylus array is provided. The stylus array includes a thin strip of magnetically permeable material secured to the undersurface of the stylus array but insulated from the styli, themselves. The permeable strip tends to modify the configuration of the magnetic field, pulling the toner bridge into intimate contact with the tips of the styli.
