CONSTITUTION:This toner consists of at least a resin, coloring agent and polyolefin wax. This resin is a styrene copolymer consisting of low mol.wt. polymers having at least one peak in 3000-80000 mol.wt. range and of high mol.wt. polymers having at least one peak in 100000-1500000 mol.wt, range in the GPC chromatogram. The polyolefin wax is polypropylene having 3000-10000 number average mol.wt. and <=0.5% volatile component. |
