Abstract (en)
[origin: EP0801333A2] A toner composition is provided comprising toner particles having a BET surface between 0.4 and 1.5 m<2>/g and a melt viscosity between 150 and 2,000 Pa.s at 120 DEG C and n different types of inorganic hydrophobic particles wherein the amount of inorganic particles is chosen such that the total BET surface of the inorganic particles relates to the BET surface of the toner particles in a specific way. In the composition sum of the BET surface of each of the types of inorganic particles multiplied with their respective weight percentage relative to the toner amount relates to the BET surface of the toner particles in a ratio BR, such that 150 ≤ BR ≤ 375. The use of the toner composition in an electrostatographic method wherein the images are fixed in a non-contact fusing step is beneficial for good gloss control.
