Abstract

It is disclosed that the yield stress of toner for use in flash fusing be adjusted by the selection of a carbon black that would increase the ability of the toner to flow, The structure factor of carbon black is the oil absorption (Dibutyiphalate absorption) number, This structure factor can change the yield stress over a wide range for toners having the same concentration of carbon black3 Therefore, one may adjust flow properties by changing the structure factor of the particular carbon black used without affect-ing the optical or electrical properties of the toner.
